Pregnancy by week

Congratulations! You’re officially into your second trimester of pregnancy. For many women (unfortunately, not all) this milestone means the end of morning sickness and a welcome boost in energy levels. Go Mama!

What's your baby up to these days? He's about the size of your fist and just might be sucking his thumb. In fact, you may be able to see this in an ultrasound at this point in your pregnancy.

Your baby's fingernails are well developed now and she's able to move her arms and legs. In fact, you may be able to feel her move in the next few weeks.

How big is your baby now? Spread one of your hands wide open—your baby is about the same size.

It might look like your baby is bulking up! Over the last week, her weight has increased about 50 percent to about 150 g. But over the next little while, her rapid growth will slow down a bit as she continues to develop.
