Strong smell

In April I had to be taken to the hospital because I was in excruciating pain it turned out to be cysts on my ovaries. I didn't have any surgery or anything I just took it easy .In August I went to the doctor because I was having issues down there. At first I was told it was just bv and a yeast infection but I still decided to get tested and got a call that it was chlamydia. I took the medicine but my only partner was told he didn't have it but he did have some kind of bacteria he also took the medicine then we waited 2 months before we started having sex again but before then I got this smell every now and again and it kind of smells like something is dying and I sometimes get pains in the same place I did when I had the problem with my ovaries. What could it be?
