Pregnancy, Month by Month
Pregnancy is a time of rapid change and development – in merely nine months, you're growing a whole person inside you. And Mom, your body is in for some dramatic changes, too.

Fetal Development in the First Trimester
During the first three months of pregnancy, which are known as the first trimester, many changes take place within the mother's body, from the fertilization of her egg to the growth of a fetus.

Baby's Early Days
Many women may not realize it, but the best time to make lifestyle changes to help ensure a healthy pregnancy and a well-developed baby is prior to conceiving.

Fetal Movement and Kick Counts
From the moment you know you're pregnant, you wait for the day you feel your baby move for the first time. Once your baby becomes active, he or she becomes somehow more real.

That First Kick
You've made it through your first trimester, and you are ready to leave behind all the nausea and fatigue problems that plagued you since your test came up positive.

A Look at Embryo Development
When most people think of pregnancy, they probably picture a woman with a large, rounded tummy who is close to giving birth.

Fetal Heart Development
Hearing your baby's heart for the first time is a never-to-be-forgotten prenatal experience. It's right up there with learning you're pregnant and the first ultrasound pictures of your baby.

The Umbilical Cord
The umbilical cord acts as your developing baby's lifeline, working constantly by carrying essential nutrients and oxygen that your little one needs for continued growth and development.

Fetal Development With Twins
Pregnancy is definitely an exciting time in a woman's life – but discovering that twins have been implanted in your uterus is unknown territory for many women.

Twin Development
Two car seats, two jackets, two security blankets and two babies. No, you're not seeing double – they're twins.
