Just took a pregnancy test and it's positive! Yay! Should I start prenatal vitamins and folic acid? Where to buy? how much? When should I go to the Dr? By my calculation I must be in week 4 right now.

Congratulations! I get my prenatals from Wal-Mart, i get the ones that have folic acid in them :) around where i live, they dont schedule your first appointment u til around 12 weeks. but you can definitely go ahead and call to schedule an appointment :)
