I had unprotected sex About 3/4 days ago with my long term boyfriend. For the past 3 days my vulva has been quite itchy and ive started to get this clear/yellowish discharge. Its uncontrollable. Its not thick or gloopy, and it doesnt exactly have a fishy smell, i cant quite explain the smell. Its not ridiculously atrong but i can smell it when i take my pants down. its more like wee, now ive never had a problem with incompetence so i know im not weeing myself. But I went the toilet earlier and it certainly felt like i had. Im just worried that this could be an sti? I found out after we had sex that hed been talking to a girl and now im terrified.
