I had unprotected sex and maybe week after had something what i thought was yeast infection. Cured that,and week after it I started having yellow discharge,very thick. After yellow discharge brown followed and finally when I was having sex started bleeding ( 2 weeks too early,not period), bleed for 8 days and now bleeding is over but yellow fish smelly discharge still appear. I'm pretty sure it's STI or STD,because i have pelvic,ovary pain as well.
