Pain in left & right sides near ovaries

I believe this pain is in my ovaries I’m not sure where my ovaries are 100% at, but I believe it to be my ovaries... the pain is on & off throughout the month and has been this way for over a year... I still get my period every month regularly and every 28/29 days.. I’m not sure what this pain is.. I haven’t got it checked out yet but I’m nervous what it might be .. does anyone have any ideas of what it might be and is it possible I can still get pregnant even with this pain and possible condition?
