What Causes Bleeding During Sex And Pain Under The Navel?

Hello, for the past two months, I ve been having midcycle periods. I m on birth control. I went to the doctors, but she thinks it is birth control related. Lately, I ve been having a really smell discharge, and it s caused sex to be very unpleasant. Sometimes, I would bleed during sex. It doesn t hurt, but there would be blood. I also have some slight pain under my belly button, on two sides, like where my ovaries are. The discharge keeps getting stronger and stronger with time. It s pink, brown, and yellow and the smell is so strong that people can smell it near me. My partner just got himself tested and he s clean on STDs, so we ruled that out as an issue. What s wrong with me? My mom has had cervical cancer, my grandma, aunt too.. I ve had the hpv vaccine, but I ve also had 17 partners,and all my partners have had many partners so this increases my chances of cervical cancer. Is this what is it?
