I need answers...

I’m desperately searching for some kind of explanation. I am not sure if I’m just ovulating late or what’s going on but my right ovary kills me at the same time every month. It’s about 4 days after i ovulate & it gives me pain when walking, having sex & all kinds of motion. I dont know if i have a cyst on my ovary or what but if you have ever had this please give me some idea on what it could be because I’m so scared.
