Today is my 4 day taking prenatal multivitamins. I am not pregnant but I am planning to get pregnant. I didn't have any sex in these month and my period already came for this month. I started to bleed today could it be because of the prenatal vitamins
No, absolutely not. All a prenatal vitamin is is basically a good mutli vitamin with extra folate. This would not impact any body functions from hormones to menses. good luck
