It happened with my first and is the same with my second. I don't see anybody ever mentioning it so maybe it's uncommon but i get so constipated with my pregnancies and the prenatal vitamin makes it worse. Anybody else experience this? Any tips on fixing the issue? I eat a serving of prunes every morning and am adding flax seed to my cereal but that only works if I'm not taking my prenatal. If i take my prenatal vitamin then i have no luck with even all the prunes and flax. Ugh plus i think it's making me super bloated and its already hard enough to eat anything with all this nauseousness.
