Watch Your Baby's Growth

Embryo to Fetus: Weeks 9 to 12 of Pregnancy
Embryo to Fetus: Weeks 9 to 12 of Pregnancy

You're well into your first trimester at this point, and your baby is growing bigger and bigger each day. Watch what it takes for her to become a fetus.

Your Changing Body

You've got a lot going on this week, mama-to-be! Your uterus has expanded enough to start showing a true baby bump, and there will likely be a little less pressure on your bladder; this means fewer trips to the bathroom. Your vision may blur slightly from fluid retention, which is normal, but give your doctor a heads-up just in case, as blurred vision can be a sign of other issues as well.

Your Developing Baby

Your baby's getting strong! You can't tell, but there's a lot of flexing muscles and rocking reflexes going on inside there, and she or she can feel when you put your hand on your tummy--but you won't be able to feel any kicking back just yet.

Your Pregnancy

This is around the time you may want to break the baby news to friends and family--and your boss! You're really starting to show, so unless you invest in some wearable tents, you won't be able to keep it a secret too much longer.
