Your Pregnancy: Week 13
Welcome to the last week of your first trimester. Any day now you'll start to feel your energy (and libido!) return. You may even be able to hold down a bite of food. Imagine that!
Take advantage of your new robust status and go out to dinner, catch a movie or take that last big pre-baby vacay. Trust us, do it now, because in a few months you'll be too big to sausage yourself into the airplane seats (even if you can afford first class!).Wondering what's up with your body, your baby and your life this week? Read on...

What You're Thinking:
"OK, fine, my skinny jeans aren't working anymore—and my "fat day" clothes don't even fit. I'm going shopping and I'm not coming back until I've got something I look fabulous in.

Your Body
Say hello to the girls! Your boobs are probably looking pretty glorious at this point. You can thank your hormones for your newfound cleavage. (Yes, those same hormones that had you hugging the porcelain throne for the past 12 weeks. See, they're not all bad!)
Estrogen and progesterone are stimulating the milk-producing glands in your boobs and making them grow, grow, grow.

Your belly may be popping out a bit now as well. If you're feeling "huge" already, just wait. You ain't seen nothing yet! All women start showing at different times in their pregnancies, so don't stress if you're not obviously pregnant ... or if you already look like you're in your 14th month.

Your Baby
Your baby can make a fist and even suck his or her thumb this week—both skills that are über-cute during infancy ... and not so much at the age of 9.
If you're really lucky, you might catch a glimpse of baby's thumb sucking on an ultrasound photo. That's a framer! Other exciting developments include:

Your baby's eyelids are fused shut to protect his eyes as they develop. His bones and skull are solidifying and soon itsy-bitsy ribs may appear. (Baby ribs! How cute is that?!) Baby's intestines are finally right where you want them—in his or her belly instead of poking out into the umbilical cord. Baby's tooth sockets are all loaded and ready to pop out baby teeth six or seven months after baby is born (causing baby a lot of pain and you a lot of lost sleep).

Who's that singing? Elton John? Could be your baby: His vocal cords and larynx are completed now. He won't be able to make any sound yet, however, because sound waves travel through air and baby is submerged in fluid.

Your baby-to-be now weighs about 20 grams and is nearly 3 inches long, or about the size of a Nutter Butter, covered in chocolate. OK, it doesn't have to be covered in chocolate, but isn't everything better that way?
