It's really not a big deal if you keep your diet together. Both my babies are perfect and no prenatals. I told my doctor I couldn't take them and he said they aren't necessary.
I take prenatal gummies with all 3 of my pregnancies. You take 2 and you're golden. Yes you do need prenatal vitamins baby needs folic acid.
You don't NEED prenatals. Keep a healthy diet and eat good, you'll be good. I didn't take any with either pregnancy.
I took the funnies with my second pregnancy.
I would just call your doctor and ask. Because not taking them can throw off your system. I don't see why you wouldn't be able to take them its just a different prenatal vitamin.
