My husband and I have been TTC since last august, with a missed month here and there for different reasons. Anyway, I’ve been taking prenatal vitamins this whole time because my Dr said to take them at least 3 months before. But since I’m still not pregnant, I’m wondering is it harmful to take these for this long and not be pregnant? I’m worried I’m getting way too many vitamins because normally a non-pregnant person wouldn’t take prenatal vitamins. Thoughts? Anyone been taking them for a very long time?
