Hi, I had protected sex on 5/24/13, had my yearly pap on 6/8/13 and everything came back negative including my STD Screening. i started having frequent urination around 6/24/13. Went in for a urinalysis & culture on 7/1/13 and everything came back negative. My symptoms of frequent urination was still present but I had protected sex again on 7/6/13. It has been almost 2 weeks since my urinalysis & culture and it's still present. I just went in on 7/16/13 for a vaginal culture to see if if I have an STDs or Vaginal Infection. I get the results tomorrow, 7/18/13 and I'm very worried and confused. If it is an STD or Vaginal Infection, why didn't this show up during my yearly?
