Day 3 of using momostat 7 and i'm bleeding?

While I wouldn't: say that bleeding on Monistat is normal, it certainly isn't unusual. There is the cervical/vaginal irritation of the yeast infection, the irritation of the applicator on a highly vascular area (cervix) and your period may have started (? early)....this happens sometimes. It probably warrants a call to your doctor's office for their recommendations. Good wishes:)
