I get yeast infections regularly, probably about every three months, especially when I have an abnormal (long) period. I have been tested for HIV and such, my doctors determined this is just a hormonal issue to which I am sensitive.

Anyways, I had abnormal spotting that turned into three weeks of bleeding recently. I discussed this with my doctor and she determined it was an issue with my birth control. Prior to this I had not had sex for 2.5 months. About a week after my period finished, I got a yeast infection. I used the one-day tricozonale (I think that’s the name for it) and waited for it to begin to work. Strangely, while the itching remained, the discharge changed from white to a pus-like yellow. There is no smell. I recently became sexually active with a new partner (during the one week between my period and getting a yeast infection), but he has been tested for STDs and came back negative. Any ideas what it could be?
