Me and my bf dry-humped 4-5 weeks ago, and then I had my periods. After that when my ovulation time over I had brown discharge which continued for 4-5 days I got worried and I went to my gp .she didn't exmine me and suggested ultrasound. My ultrasound is done after 3-4 days of discharge. It's normal. But my brown discharge started again and my periods are not coming. So I am really worried abt sti and pregnancy. I can't go for culture test bcoz my gync gave me feprox ctp vaginal tablets and she said after that you can't go for culture test for next 4-5 days .my concern is why I am having this brown discharge .my tsh levels were checked in april and it's in normal range .is there any chance that semen or precum can come through jeans and gave me infection. Other symptoms are abdominal pain and backache. With body pain .and in august-sep I felt feverish some days .i am really scared. please help me out.
