I wud always check with the doctor before using anything over the counter. Just to be on the safe side. If something over the counter will work there's no reason they won't ok it so it's always safer to check first. I wud hate to use something that may have a negative effect on my pregnancy. Good luck!!
For OTC meds do Monistat 7 ( the 7 day cream ) and do it right before bed at night ... If you go to your doc they will proscribe you one pill that stays in your system for 7 days but does nothing for the itching at all..
