Baby:Your baby, now about in its 15th week of development, measures
about 4.4 to 4.8 inches from crown to rump and has doubled in weight in the
last two weeks to about 3.5 ounces. Fat begins to form, helping your baby's
heat production and metabolism. The lungs are beginning to exhale amniotic
fluid, and the circulatory and urinary systems are working. Hair on head,
eyebrows and eyelashes is filling in.
Mom-to-be: You're showing more now, with an obvious swelling in your
lower abdomen. A five- to 10-pound weight gain is typical by now. You also may
be noticing an increase in appetite.
Pregnancy Week by Week
If you are newly pregnant, or trying to conceive, you have many questions about what to expect. How will your body change? What's happening inside you? Here's what to expect week by week.
Tip of the Week: Change positions slowly, especially when you move
from a lying down position to sitting or from a sitting position to standing to
avoid feeling dizzy or faint. If you feel lightheaded, sit down and lower your
head, or lie down for a moment.
Baby: Your baby measures 5 to 5.6 inches from crown to rump and
weighs about 5.25 ounces. The rapid growth spurt is tapering off, but reflexes
are kicking in. It can yawn, stretch and make facial expressions, even frown.
Taste buds are beginning to develop and can distinguish sweet from bitter
tastes. The baby will suck if its lips are stroked and it can swallow, and even
get the hiccups. The retinas have become sensitive to light, so if a bright
light is shined on your abdomen, baby will probably move to shield its
Mom-to-be: Your uterus, about the size of a cantaloupe, can probably
be felt just below your navel. You're most likely feeling the baby move by now.
A mid-pregnancy ultrasound may be performed between now and 22 weeks to assess
fetal growth and development and to verify the due date. If the baby is in the
right position, the ultrasound may even be able to determine whether it's a boy
or a girl. Your heart has to work 40 percent to 50 percent harder now to
support your pregnancy.
Tip for the Week: Suggest that your partner go with you for the
ultrasound. It's a chance to catch the first glimpse of your baby together, as
well as provide a snapshot to show friends and family later. Sonograms still
don't guarantee a healthy baby, but they can provide reassurance and spot some
Baby: Your baby measures about 5.2 to 6 inches from crown to rump and
weighs about 7 ounces. Skin is developing and transparent, appearing red
because blood vessels are visible through it. Creamy white protective coating,
called vernix, begins to develop.
Mom-to-be: As your baby continues to grow, you may be feeling some
mid-pregnancy aches and pains by now -- lower abdominal achiness, dizziness,
heartburn, constipation, leg cramps, mild swelling of ankles and feet, and a
backache. Dilated blood vessels might cause tiny, temporary red marks (called
spider nevi) on your face, shoulders and arms.
Tip of the Week: Take care not to get overtired since rapid growth of
the baby can compound the burden on your heart, lungs and kidneys.
