Your Baby at 12 Weeks Pregnant
Your little one is the size of a passion fruit (length: 2.5”; weight: 0.5 oz.).
Nail works. Those little nail beds are sprouting nails, so stand by with a nail clipper. Many babies are actually born with long fingernails that need to be trimmed soon after delivery.
Parts in place. The truly critical period for your little one's development is coming to a close. By the end of this week, all the body parts will be there; even the sex organs have developed (although it's too soon to determine whether you're carrying a girl or a boy).
Lights out. At 12 weeks, the eyelids have formed and will close. They'll remain fused together until late in your second trimester.
Your Pregnancy at 12 Weeks
Feed me! As the nausea and discomfort of early pregnancy subside, you may find that you have your appetite back — and then some! Around this week, many women report feeling that "the baby is hungry." Be sure you're eating enough, and maintaining a healthy diet, but don't feel you actually need to eat for two.
What's normal, what's not. As your blood volume increases to keep your little one nourished, you may find that your gums are more sensitive and bleed when you brush or floss. While this can be disconcerting, it's completely normal.
