Pain during sex

Em
Hey girls, I was diagnosed almost 3 years ago and had it all cleaned out and am headed back next month for my regular check up. The last few months my symptoms have been coming back full force and I'm miserable but this time I'm having sharp sharp pain in my right ovary everytime I have sex with my boyfriend. He's the only man I have ever been with so I don't believe it's an std or anything, but I am wondering if this is common or if it's something else I should be worried about ...
