Most pregnancies are medically uneventful and end happily in the birth of a healthy baby. Your first  and most important step is to sign up for a comprehensive prenatal program with an obstetrician (a doctor who specializes in pregnancy and childbirth) or a midwife. You and your developing baby will get routine monitoring to make sure everything is going well, and if it isn't, you'll get a referral for appropriate care. You will get reliable information about each stage of your pregnancy, including labor, childbirth, and the care and feeding of a newborn.

Pregnancy brings many changes to your body. And  you may wonder whether certain physical discomforts are serious enough for medical intervention or are minor problems you can deal with on your own. 

You'll have various kinds of discomforts during pregnancy – some fleeting and others that last longer. Some may happen in the early weeks, while others emerge closer to the time of delivery. Still others may start early and then go away, only to return later.

Every person's pregnancy is unique, so you may not have all of the changes described below.

Talk to your doctor if:

Most pregnant women will feel some changes in their breasts. Your breasts will get bigger as your milk glands enlarge and the fat tissue enlarges, causing breast firmness and tenderness, typically during pregnancy's first and last few months. Bluish veins may also appear as your blood supply increases. Your breasts might leak a yellowish fluid called colostrum, usually during the third trimester. Colostrum is the “pre-milk” that will nourish your baby in the first days of life until your milk comes in. As you get closer to delivery, it changes to a thin, colorless liquid.

Your nipples can also darken. They may stick out more, and the areolas may get bigger. Small glands around the nipples become raised. They make oil to keep your nipples soft. These changes make it easier for your baby to find and latch onto your nipples for breastfeeding.

The freckles and moles on your body may be darker, too. Talk to your doctor if you have a mole or freckle that is growing, changing color and shape, itching or bleeding, or larger than a pencil eraser. These may be signs of skin cancer.


  •  Wear a bra that provides firm support.
  •  Choose cotton bras or those made from other natural fibers.
  •  Get a bigger bra as your breasts become larger and fuller. Your bra should fit well without irritating your nipples. Try maternity or nursing bras, which provide more support and can be used after pregnancy if you choose to breastfeed.
  •  Try wearing a bra during the night.
  •  Tuck a cotton handkerchief or gauze pad into each bra cup to absorb leaking fluid. You can also buy nursing pads in the drugstore or maternity/baby store that fit into your bra. Make sure to change these pads as needed so your skin doesn't get irritated.
  •  Wash your breasts with warm water and mild soap that will not cause dryness.

Feeling tired? That might be because your growing baby requires extra energy. Sometimes, it's a sign of anemia (low iron in the blood), which is common during pregnancy.


  • Get plenty of rest. Go to bed earlier and take naps.
  • Keep a regular schedule when possible.
  • Pace yourself. Balance activity with rest.
  • Moderate exercise daily boosts your energy level.
  • Ask your health care provider to test your blood routinely for anemia.

It's very common and normal to have an upset stomach when you're pregnant.

Chalk it up to pregnancy's hormonal changes. It usually happens early in pregnancy, while your body is adjusting to the higher hormone levels.

Good news: Nausea usually disappears by the fourth month of pregnancy (although in some cases it can persist throughout the pregnancy). It can happen at any time of the day but may be worse in the morning, when your stomach is empty (that's why it's called "morning sickness") or if you aren't eating enough.


  • If nausea is a problem in the morning, eat dry foods like cereal, toast, or crackers before getting out of bed. Try eating a high-protein snack such as lean meat or cheese before going to bed. (Protein takes longer to digest.)
  • If you are hungry but extremely nauseated, try the BRAT (bananas, rice, and tea) diet as well as bland foods.
  • Acupressure wristbands offer some pregnant women comfort.
  • Ginger may combat nausea.
  • Eat small meals or snacks every 2 to 3 hours rather than three large meals. Eat slowly, and chew your food completely.
  • Sip on fluids throughout the day. Avoid large amounts of fluids at one time. Try cool, clear fruit juices, such as apple juice or grape juice.
  • Avoid spicy, fried, or greasy foods.
  • If you are bothered by strong smells, eat foods cold or at room temperature to minimize or avoid odors that bother you.
  • Talk to your doctor about taking vitamin B6. Other natural treatments and prescription medications can provide relief.
  • Contact your health care provider if your vomiting is constant or so severe that you can't keep fluids or foods down. This can cause dehydration and should be treated right away.

Diarrhea usually doesn't mean anything is wrong. But it can be distressing. It may be related to your prenatal vitamin or your attempts to eat better, or it could just be a bug you caught. In any case, when diarrhea strikes during pregnancy, it's even more important to take good care of yourself.

Call your doctor if the diarrhea is serious or lasts more than 24 hours, if you get dehydrated or dizzy, if the stool has blood or pus, if it's black and tarry, if you also have a fever or severe belly pain, or if you think medication might help ease your symptoms.


  • Eat bland, soft, and low-fiber foods such as bananas, rice, toast, mashed potatoes, yogurt, or cottage cheese.
  • Drink plenty of water and electrolyte drinks such as Gatorade or Pedialyte to replace lost fluids. (If you have gestational diabetes, check with your doctor first.) It's especially dangerous to become dehydrated during pregnancy. Dehydration can trigger preterm contractions.

Your pants may feel tight even if you're not that far along. Blame hormone changes. Early in pregnancy, rising progesterone can cause your digestive system to slow and your smooth muscle tissue to relax. This can cause bloating. It's similar to what happens to many women right before their period starts.


It's normal to have to pee a lot when you're pregnant. Early in your pregnancy, your body makes a hormone that may increase urination. Your growing uterus and baby also press against your bladder. The pressure can wake you up several times a night to go to the bathroom. You may also have the urge to go even when your bladder is almost empty. This problem usually goes away a few days after your baby is born.

Call your doctor if you have a fever or blood in your urine, or if you have the urge to go again just after you've emptied your bladder. If it hurts, burns, or stings when you pee, you could have a urinary tract infection. This needs treatment right away.


  • Don't wear tight-fitting underwear, pants, or pantyhose.
  • Drink plenty of fluids to avoid dehydration. Try to get them mostly during the day. Drink less in the evening and at night. This should help you cut back on nighttime bathroom visits.
  • Avoid coffee, tea, colas, and other caffeinated drinks. These can make you urinate more often.

Headaches can happen anytime during pregnancy. They can be caused by tension, congestion, constipation, or in some cases, preeclampsia (detected after 20 weeks).


  • Put an ice pack on your forehead or the back of your neck.
  • Rest, sit, or lie quietly in a low-lit room. Close your eyes and try to relax your back, neck, and shoulders.
  • Over-the-counter acetaminophen may help. But if your headaches don't go away, are severe, make you nauseated, or affect your vision, tell your doctor.

You may not have expected pregnancy to affect your mouth. But your blood circulation and hormone levels can make your gums tender and swollen, and you may notice they bleed more easily. You may also get nosebleeds.


  • Get a dental checkup early in your pregnancy to make sure your teeth and mouth are healthy. See your dentist if you notice a particular problem.
  • Brush your teeth, floss regularly, and rinse daily with an antiseptic mouthwash.

Your hormones, as well as vitamins and iron supplements, may cause constipation (trouble pooping or incomplete or infrequent passage of hard stools). Pressure on your rectum from your uterus may also cause constipation.

Call your doctor if you also have belly pain or rectal bleeding. If iron supplements are causing constipation, they may recommend a different one.


  •  Add more fiber (such as whole-grain foods, fresh fruits, and vegetables) to your diet.
  •  Drink plenty of fluids daily (at least 6-8 glasses of water and 1-2 glasses of fruit or prune juice).
  •  Drink warm liquids, especially in the morning.
  •  Exercise daily. Walking and swimming are activities that are gentle on your pregnant body.
  •  Avoid straining when you have a bowel movement.
  • Talk with your doctor about a laxative or stool softener.

You might be surprised that carrying a baby could cause pain in your wrist. But up to 35% of women get pain or weakness in their wrist during pregnancy, usually in the third trimester. Fluid retention puts more pressure on the carpal tunnel, which runs from your wrist to the bottom of your palm. Most likely, the pain will get better within a few months of your baby's birth.

Call your doctor if you have numbness, tingling, or pain in your hand or wrist, or if you have pain or strange sensations traveling up your arm to your shoulder.


  • Do range-of-motion exercises that stretch your wrist.
  • Apply ice for pain.
  • Avoid repetitive wrist and hand motions, or positions or activities that make pain or numbness worse. Wear a wrist splint if your job requires repetitive motions.
  • If computer work is causing pain, adjust your chair or keyboard height to change the position of your wrists.
  • Wear a wrist splint to bed if you have pain at night. It keeps your wrists from curling while you sleep, which contributes to pain.

Dizziness can occur anytime during middle to late pregnancy. Here's why it happens:

  • The hormone progesterone dilates blood vessels, so blood tends to pool in the legs.
  • More blood is also going to your growing uterus. This can cause a drop in blood pressure, especially when changing positions – and that can make you dizzy. If your blood sugar levels get too low, you may feel faint.


  • Move around often when standing for long periods of time.
  • Lie on your left side to rest. This helps circulation throughout your body.
  • Avoid sudden movements. Move slowly when standing from a sitting position.
  • Eat regular, small meals throughout the day to prevent low blood sugar.
  • Drink plenty of water.


Finding a comfortable resting position can become difficult later in pregnancy. And your ballooning belly and bathroom breaks aren't the only things keeping you up. From backaches to heartburn to anxiety, a wide range of concerns can affect slumber. Hormones can also disrupt your sleep patterns, leaving you exhausted by day and wide awake by night.

Even though you may not be sleeping well, now is when you need sleep the most. Your body needs to rest so it can feed and house your growing baby.


  • Don't take sleep medication.
  • Try drinking warm milk at bedtime.
  • Take a warm shower or bath before bedtime.
  • Use extra pillows for support while sleeping. Lying on your side, place a pillow under your abdomen, behind your back, and between your knees to prevent muscle strain and help you get the rest you need.
  • Use blocks to prop up the head of the bed a few inches. This can ease breathing and help prevent any backflow of stomach acid from reflux.
  • You will probably feel better lying on your left side; this improves circulation of blood throughout your body.  Sleep with bent knees to take pressure off your back.
  • Exercise. Every day, try to take a 30-minute walk or a pregnancy exercise class. Staying active can help you sleep better. Just do it early in the day. Exercising within 4 hours of bedtime can be stimulating enough to keep you up.
  • Relax before bed. Try a pregnancy yoga video or some deep-breathing exercises.
  • Stretch. Do a few leg stretches to keep your legs from cramping during the night.
  • Limit drinks. Stop drinking within 2 or 3 hours of bedtime so you won't have to get up and go to the bathroom in the middle of the night.
  • Avoid late meals as well as spicy, greasy, or acidic foods close to bedtime.
  • Pee before sleeping. Make one last trip to the bathroom before you turn out the light.
  • Turn down the thermostat. You're going to feel warmer now because extra blood is rushing to your skin. Keeping your bedroom cool will make you more comfortable and prevent you from having to kick off the covers in the middle of the night.

Heartburn is a burning feeling that starts in the stomach and seems to rise up to the throat. During pregnancy, changing hormone levels slow down your digestive system, weaken the stomach sphincter, and your uterus can crowd your stomach, pushing stomach acids upward.


  • Eat several small meals each day instead of three large meals.
  • Eat slowly.
  • Drink warm liquids.
  • Avoid fried, spicy, or rich foods, or any foods that seem to give you indigestion.
  •  Don't lie down right after eating.
  •  Keep the head of your bed higher than the foot of your bed. Or place pillows under your shoulders to prevent stomach acids from rising into your throat.
  •  Don't mix fatty foods with sweets in one meal, and try to separate liquids and solids at meals.
  • Try heartburn relievers such as Gaviscon, Maalox, Mylanta, Riopan, Titralac, or Tums.

Hemorrhoids are swollen veins that appear as painful lumps on the anus. During pregnancy, they may form as a result of increased circulation and pressure on the rectum and vagina from your growing baby.


  • Try to avoid constipation. Constipation can cause hemorrhoids and will make them more painful.
  • Avoid sitting or standing for long periods of time; change your position frequently.
  • Don't strain during a bowel movement.
  • Apply ice packs or cold compresses to the area, or take a warm bath a few times a day to provide relief.
  • Avoid tight-fitting underwear, pants, or pantyhose.
  • If you still need more help, consult your health care provider.

Pregnancy hormones may cause the walls of your veins to weaken and swell. Pressure on the veins behind your uterus also slows the circulation of blood to your heart, making the smaller veins in your pelvis and legs swell. You're most likely to get these bluish, swollen veins in your legs. But in late pregnancy, they may appear in your vulva, the area outside your vagina. Varicose veins will probably get better after your baby is born, when pressure on your veins goes away.

Call your doctor if the veins feel hard, warm, or painful, or if the skin over them looks red.


Although varicose veins usually run in families, these things might help:

  • Avoid standing or sitting in one place for long periods. It's important to get up and move around often.
  • Avoid remaining in any position that might restrict the circulation in your legs (such as crossing your legs while sitting).
  • Elevate your legs and feet while sitting.
  • Exercise regularly.
  • Wear support hose. Avoid socks or knee-highs that are too tight or constraining.
  •  Sleep or rest on your left side to ease pressure on the vein that carries blood from your feet to your heart. It's on your right side.

Pressure from your growing uterus can cause leg cramps or sharp pains down your legs.


  • Be sure to eat and drink foods that are rich in calcium (such as milk, broccoli, or cheese).
  • Wear comfortable low-heeled shoes.
  • Try wearing support hose, but avoid any leg wear that is too tight.
  • Elevate your legs when possible; avoid crossing your legs.
  • Exercise daily.
  • Stretch your legs before going to bed.
  • Avoid lying on your back, since the weight of your body and the pressure of your enlarged uterus can slow the circulation in your legs, causing cramps.
  • Gently stretch any muscle that becomes cramped by straightening your leg, flexing your foot, and pulling your toes toward you.
  • Massage the cramp or apply heat or a hot water bottle to the sore area.

You may have a stuffy nose or feel like you have a cold. Pregnancy hormones sometimes dry out the nose's lining, making it inflamed and swollen.


  • Apply a warm, wet washcloth to your cheeks, eyes, and nose to reduce congestion.
  • Avoid using nasal sprays unless prescribed by your doctor because they can aggravate your symptoms.
  • Drink plenty of fluids (at least 6-8 glasses of fluids a day) to thin mucus.
  • Elevate your head with an extra pillow while sleeping to prevent mucus from blocking your throat.
  • Use a humidifier or vaporizer to add moisture to the air.
  • Take a warm shower or bath.
  • Get vaccinated against the flu. When you're pregnant, you're more likely to get sick and have serious complications, compared to when you're not pregnant.

Shortness of breath can happen due to increased upward pressure from the uterus and changes in lung function.


  • When walking, slow down and rest a few moments.
  • Raise your arms over your head (this lifts your rib cage and allows you to breathe in more air).
  • Avoid lying flat on your back, and try sleeping with your head elevated.
  • If prolonged shortness of breath continues or you have sharp pain when inhaling, contact your health care provider. You could have a pulmonary embolism (blood clot in the lungs).

Stretch marks are a type of scar tissue that forms when the skin's normal elasticity is not enough for the stretching that occurs during pregnancy. They usually appear on the belly and can also appear on the breasts, buttocks, or thighs.

Though they won't disappear, stretch marks will fade after delivery. Stretch marks affect the surface under the skin and are not preventable.


  • Be sure that your diet contains enough sources of the nutrients needed for healthy skin (especially vitamins C and E).
  • Apply lotion to your skin to keep it soft and reduce dryness.
  • Exercise daily.

Pressure from your growing uterus on the blood vessels carrying blood from the lower body causes fluid buildup. The result is swelling (edema) in the legs and feet.

Extra weight during pregnancy can also make your feet bigger. Plus, pregnancy hormones loosen your ligaments and muscles so your pelvic joints open up to get ready for childbirth. This affects your whole body, even your feet. Call your doctor if any swelling is more than mild or if it suddenly gets worse.


  • Try not to stay on your feet for long periods of time. Avoid standing in one place.
  • Drink plenty of fluids (at least 6-8 glasses of fluids a day).
  • Avoid foods high in salt (sodium).
  • Elevate your legs and feet while sitting. Avoid crossing your legs.
  • Wear loose, comfortable clothing; tight clothing can slow circulation and increase fluid retention.
  • Soak your feet in cool water.
  • Keep moving. Exercise your legs to keep fluid from building up.
  • Don't wear tight shoes; choose supportive shoes with low, wide heels.
  • Keep your diet rich in protein; too little protein can cause fluid retention.
  • Notify your health care provider if your hands or face swell. This may be a warning sign of preeclampsia.
  • Rest on your side during the day to help increase blood flow to your kidneys.

This won't happen in most pregnancies. But pregnancy does mean a greater chance of developing a blood clot.

A blood clot in the calf may lead to pain or swelling and can result in a blood clot that travels to the lung, which could be fatal.

A blood clot in the brain may bring a severe headache. But there are other possible causes of bad headaches during pregnancy.

Recommendation: If you have a history of blood clots, or if you get a severe headache, consult your doctor.

Vaginal bleeding during pregnancy: Call your obstetrician if you have spotting or bleeding at any point during your pregnancy. It's more likely to be serious if it's heavy bleeding or if it happens later during pregnancy. But call your doctor, regardless. 

Other vaginal discharge: It's normal for this to increase when you're pregnant. It happens due to greater blood supply and hormones. Normal vaginal discharge is white or clear, isn't irritating, is odorless, and may look yellow when dry on your underwear or panty liners.


  • Choose cotton underwear or brands made from other natural fibers.
  • Avoid tight-fitting jeans or pants.
  • Do not douche. Douching can introduce air into your circulatory system or break your bag of waters in later pregnancy.
  • Clean the vaginal area often with soap and water.
  • Wipe yourself from front to back.
  • Contact your health care provider if you have burning, itching, irritation or swelling, a bad odor, bloody discharge, or bright yellow or green discharge. (These symptoms could be a sign of infection.)

Backaches are usually caused by the strain put on the back muscles, changing hormone levels, and changes in your posture.


  • Wear low-heeled (but not flat) shoes.
  • Avoid lifting heavy objects.
  • Squat with your knees bent when picking things up instead of bending down at the waist.
  • Don't stand on your feet for long periods. If you need to stand for long periods, place one foot on a stool or box for support.
  • Sit in a chair with good back support, or place a small pillow behind your lower back. Also, place your feet on a footrest or stool.
  • Check that your bed is firm. If needed, put a board between the mattress and box spring.
  • Sleep on your left side with a pillow between your legs for support.
  • Apply a hot water bottle or heating pad on low setting to your back, take a warm bath or shower, or try massage.
  • Perform exercises, as advised by your health care provider, to make your back muscles stronger and help relieve the soreness.
  • Maintain good posture. Standing up straight will ease the strain on your back.
  • Contact your health care provider if you have a low backache that goes around your stomach and does not go away within one hour after you change position or rest. This might be a sign of premature labor.

Sharp, shooting pains on either side of your stomach may result from the stretching tissue supporting your growing uterus. These pains may also travel down your thigh and into your leg.


  • Change your position or activity until you are comfortable; avoid sharp turns or movements.
  • If you have a sudden pain in your belly, bend forward to the point of pain to relieve tension and relax the tissue.
  • Apply a hot water bottle or heating pad to your back, or take a warm bath or shower.
  • Try a massage.
  • Make sure you are getting enough fluids.
  • Take acetaminophen now and then.Follow the dosing instructions on the label.
  • Contact your health care provider if the pain is severe or constant, or if you are less than 36 weeks pregnant and you have signs of labor. (Signs of labor include repetitive cramping like contractions.)


If you have certain medical conditions – such as thyroid disease, diabetes, high blood pressure, asthma, and/or lupus – note any changes in your condition during pregnancy and tell your doctor about them. It's important to have those conditions under good control, for the sake of your health and your baby's health. 

For example, people with diabetes whose blood sugar levels get too high may be more likely to have a miscarriage. And if you have high blood pressure while pregnant, the baby may be more likely to be born preterm (before 37 weeks of pregnancy) . 

Recommendation: Be sure to keep up with managing any conditions, ideally starting before you conceive and throughout your pregnancy.  


The uterine muscles will contract (tighten) starting as early as the second trimester of pregnancy. Irregular, infrequent contractions are called Braxton-Hicks contractions (also known as "false labor pains"). These are normal during pregnancy.


  • Try to relax
  • Change positions. Sometimes this can ease the contractions.
  • Call your doctor if they do not go away.

What does it mean if your baby has been active but now seems to have less energy? It may be normal. But how can you tell?

Call your doctor right away if you notice a big change in how much your baby is moving. Your doctor has monitoring equipment that can be used to determine if the baby is moving and growing well.

You'll want to be aware of what is normal for your baby. There's no hard and fast number of times that you should feel the baby kick or move. But you'll want to know what's typical for your baby and reach out to your obstetrician if you notice a big change in how active the baby is.

To get to know your baby's patterns, you can count the number of kicks that happen in an hour. Or, you can measure how long it takes for your baby to kick 10 times. Some experts recommend calling your doctor if you haven't felt at least 10 kicks within 2 hours to check on the baby.

When you're pregnant, your enlarged uterus can put pressure on your bladder. That could lead to a urine leak, which you might mistake for your water breaking in a more subtle, less dramatic way than you might have expected. (It's not always a big gush of fluid.)

One way to tell the difference is to go to the bathroom and pee. After your bladder is empty, if you're still noticing fluid, your water has broken. Call your doctor or go to the hospital.
