Today, at 11dpo, I received a quick positive! This will be baby number 4 and we have been TTC since April. Hoping our girl sway was successful, but will be blessed either way. I have been taking 1600mcg of Folic acid a day along with 5000iu of vitamin d3 weekly, and 18mg iron and 15MG zinc 3x week. How do I go about changing to a prenatal vitamin? I think the prenatal I was looking at had 1000mg of folic acid.
