Watch Your Baby's Growth
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
Until now, your uterus has fit snugly within your pelvis. But as it begins to move north this week, the pressure on your bladder should start to let up a bit. This also means your belly has the room to swell, giving you that slightly rounded, "Yes, I'm pregnant!" look. And if your world is a little blurrier than usual, don't be alarmed.
Your Developing Baby
As your baby's muscles start to bulk up at this stage, he's getting busy stretching and kicking. When you put your hand on your belly, your baby will likely wiggle in response because his reflexes are starting to develop -- though it's too early to feel his movements.
Tip of the Week
Many couples decide to break the news around the end of the first trimester. If you're not ready to spread the word yet, start thinking about how you'll spill the beans and get ready to tell your boss that you're pregnant. Handle it like any other important discussion: Set up a one-on-one -- and be prepared.
