wow, I've never heard that folic acid is bad after the 12th week. I did take a supplement with folic acid (the max amount) through my entire pregnancy. a study I read about last week or the week before has found that taking folic acid consistently for a year before you conceived and then continued after you conceive cut miscarriage rate immensely (or was it birth defects? I honestly don't remember). I thought that was remarkable, because I never knew you should take it for that long before conceiving... sorry, not really any help. I say take it, but what do I know?
