Your doctor should have an on call nurse you can talk to, when I thought I had a yeast infection, she had me come in and swabbed me called me back that day and ordered me a prescription for a yeast infection. The doctor told me not to use any creams or itch relieve that I needed to wash really well and wear a panty linear or pad to draw the moisture away
My doctor told me I was not supposed to take the pill for yeast infections while pregnant. Monistat 7 is safe though! I used it and it's on the safe list and confirmed by my doctor and it's just over the counter (:
