Prenatals making me sick???? TMI

Hi everyone. So I started taking my prenatals right when I found out I was pregnant a few days ago, but in the meantime I have been going to the bathroom more frequently and I have had really bad gas to go along with it. Is this normal??? Or is it just apart of pregnancy??? I never have to go "number 2" this much... normally it's only 1 time a day, maybe 2. I'm now going 3-4 and it's almost diarrhea... along with really bad gas. Anyone else expierence this???? Please help!
