well congrats! you can find a lot of support here, I'm terra and im 16 but i have no babies.
one of the first things the girls here will tell you would be to go to the doctor, they'll ask you about your family history and prescribe you some prenatal vitamins! you might also want to post in the pregnancy forum, you'll probably get a lot more responses over there, this part of the forum fizzled out a few months ago!
