I had unprotected sex on the 1st of the month and now it's the 23. I have had severe itching around my vagina for about 4 or 5 days. I went to the doctor and she told me I have a yeast infection. I have been taking the medicine for about 3 days and eveything has gotten a better but the bumps that were little and only around the vaginal opening seem to be spreading around my butt... What does this mean??
