Hi mama! Since your OB specifically told you to continue taking conzace, I'd trust that, doctors prescribe it kaya alam nila ang safe dosage for pregnancy, hindi naman sila magbibigay ng harmful stuff. A few of my mum friends took similar vitamin combos throughout pregnancy based on their doctor's advice, and they were fine. But if you're worried about the vit A, C, E levels, best to clarify directly with your OB so you have peace of mind, they can explain exactly kung bakit okay ang dosage for you specifically. Take care, mama!
