I don't have my primary health doctor yet (will in the next week or so) but when I went to the hospital they prescribed me some. I went to local stores and they pointed out different prenatals.. I got the one a day ones... However, I was on them for about 5 days and my back became blotchy and a rash broke out. So I stopped and about 3'days later it was gone and no more itching. Should I try a different brand or wait til I go to my doctor? Thanks!!
