Feeling very tired is normal in pregnancy, starting early on.
A woman can start feeling unusually fatigued as soon as one week after conceiving.
Why? It's often related to a high level of a hormone called progesterone, although other things -- such as lower levels of blood sugar, lower blood pressure, and a boost in blood production -- can all contribute.
If fatigue is related to pregnancy, it's important to get plenty of rest. Eating foods that are rich in protein and iron can help offset it.
Nausea (Morning Sickness)
Morning sickness is a famous symptom of pregnancy. But not every pregnant woman gets it.
Here's why it happens. A pregnant woman's hormone levels can slow the emptying of her stomach. That contributes to nausea, often called morning sickness, though it can happen at any time during the day.
Also, some women crave, or can't stand, certain foods when they become pregnant. That's also related to hormonal changes. The effect can be so strong that even the thought of what used to be a favorite food can turn a pregnant woman's stomach.
It's possible that the nausea, cravings, and food aversions can last for the entire pregnancy. Fortunately, the symptoms lessen for many women at about the 13th or 14th week of their pregnancy.
In the meantime, be sure to eat a healthy diet so that you and your developing baby get essential nutrients. You can talk to your doctor for advice on that.
The most obvious early symptom of pregnancy -- and the one that prompts most women to get a pregnancy test -- is a missed period. But not all missed or delayed periods are caused by pregnancy.
Also, women can experience some bleeding during pregnancy. If you are pregnant, ask your doctor what you should be aware of with bleeding. For example, when is bleeding normal and when is it a sign of an emergency?
There are reasons, besides pregnancy, for missing a period. it might be that you gained or lost too much weight. Hormonal problems, fatigue, or stress are other possibilities. Some women miss their period when they stop taking birth control pills. But if a period is late and pregnancy is a possibility, you may want to get a pregnancy test.
Other Early Symptoms of Pregnancy
Pregnancy brings changes in your hormonal balance. And that can cause other symptoms..
Frequent urination. For many women, this starts around the sixth or eighth week after conception. Although this could be caused by a urinary tract infection, diabetes, or overusing diuretics, if you're pregnant, it's most likely due to hormonal levels.
Constipation. During pregnancy, higher levels of the hormone progesterone can make you constipated. Progesterone causes food to pass more slowly through your intestines. To ease the problem, drink plenty of water, exercise, and eat plenty of high-fiber foods.
Mood swings. These are common, especially during the first trimester. These are also related to changes in hormones.
Headaches and back pain. Many pregnant women report frequent mild headaches, and others experience chronic back pain.
and fainting. These may be related to dilating blood vessels, lower blood pressure, and lower blood sugar.
A pregnant woman could have all of these symptoms, or maybe have only one or two. If any of these symptoms become bothersome, talk with your doctor about them so you can make a plan to offset them.
