Prenatal vitamins making me sick

Mel

So I've been taking over the counter prenatal (Ill be 8 weeks tomorrow) because my dr said she'll prescribe me some once I'm all out of these but these are making me nauseous! I swear the only times I feel nauseous is after taking them which is so weird to me. Should I just ask her to prescribe me some instead? 😭 idk if that will even make it better or what the differences in them will be
