13 weeks

Yay! It’s the last week of the first trimester and you did it. We’re not just talking about getting through those work meetings without falling asleep (or puking!), we’re talking about how you’ve completed one whole third of your pregnancy -- and the reputed toughest one at that. You’ve grown a fetus that has vocal cords, teeth and even fingerprints (wow!) and you probably kept this incredible news (mostly) secret while you constantly wished you could shout it from the rooftops -- or, at the very least, use it as an excuse for getting to work late. It’s about this time that many parents-to-be start spreading the word (to more people than just close family and friends) that there’s a baby on the way. But know that there are no hard and fast rules about when you should divulge your secret. It could be after your next prenatal doctor visit, once you start showing or at a big family event where everyone will be gathered. Or maybe everyone already knows! That’s totally your call.

your baby's the size of a peach!

It's about 2.9 inches long and weighs about .81 ounces, and -- proportion-wise -- it's head's now about 1/3 the size of her body (remember? It used to be bigger!).

your baby at 13 weeks

• Can you believe it's forming vocal cords and teeth?!
• And even though it's still teeny,  it already has fingerprints.
• It's intestines are moving from the umbilical cord to their more permanent place, in it's tummy.
