Prenatal vitamins and you

So this morning I’m feeling sick as a dog. I’ve been horribly constipated and my boyfriend made me a cup of “Smooth Move Tea” and omg I swear I was pooping all night lol. So I wake up this morning after horrible sleep from pooping all night and this morning my boyfriend says “well I bet you’re not bloated!” And I’m not I’m just so sick 😷. So I take my prenatal “Premama” and boom within 5 minutes my symptoms are GONE! Anyone have a similar experience? Anyone’s prenatal make them sick instead? Maybe we can get a good list going!
