Vitamin during pregnancy? What do you consume?

Hi mummies, could you please share the vitamins that you are taking on 2nd tri and 3rd tri? I am currently week 30 but noticed cramp here and there, back pain and bleeding gum sometimes - when i google it says lack of calcium and magnesium. My friend also said could be i lack or calcium. The only vitamin i am taking right now is prenatal vitamin. I asked my gynae if i shd take calcium he say no need and all those symptoms are normal🫤 #firsttimemom #advicepls #FTM
