pain in left ovary?

I did a cycle on gonal f in late june, early july, only 1 follicle developed, resulted in a bfn. I have been having slight pain and burning, in my left ovary area sine early july and it is also tender in the area, I am currently on bcp. I see Re on tues and will tell him, I did tell him before trigger and iui in july and he just thought it was from the gonal f, but it shouldn't still feel like this right? any ideas of what it could be?
