Week 12 of Pregnancy: Fetal Organs and Systems
This week marks a turning point for your baby. At 12 weeks pregnant, the herculean task of developing new bodily structures is nearing an end as most of your baby's systems are fully formed. Now comes the maintenance phase, during which your fetus' systems continue to mature for the next 28 weeks and the organs get to work. Your little fetus weighs as much as half an ounce now, and the crown-to-rump length is about two and a half inches (the size of a large plum — busily working his or her way through the whole produce department). It's hard to believe (especially from the outside, since you're probably barely showing at this point), but your baby has more than doubled in size during the past three weeks. And that's just on the outside — there's plenty going on inside too. The fetal digestive system is beginning to flex its digestive muscle — literally — as it starts practicing contraction movements, a skill your baby will need after birth to push food through the digestive tract. The pituitary gland at the base of the brain has started producing hormones. And the bone marrow is making white blood cells, which will one day help your baby fight infection (including all those germs passed around the snot-nosed playgroup).
This week, your baby's fingernails and toenails will appear! How adorable is that? Your baby's also likely spending his days stretching his newly formed limbs, but sit tight. You won't feel his soccer player kicks for a few more weeks yet.

L.O.L. This made me laugh so I'm going to share. I TOTALLY felt like this a couple weeks ago. But it has been confirmed there is only ONE little bitsy in there, so we're good.
