Had unprotected sex recently and noticed some symptoms couple days later. My vagina was sore, and I noticed a watery discharge. I went to the doctor and she said it was bacterial infection now days later I was still experiencing symptoms after taking prescription medicine. Went back she mention yeast infection from antibiotics and the diflucan worked a little...but now I'm nervous because I felt pressure in my lower abdomen the other day and the day before that I thought I felt something worm ish in my anus..and I'm not sure if I have blisters on my buttocks right underneath the vaginal opening or just a rash I haven't noticed any bumps anywhere else. Not sure what's going on.
