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.

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
