For the last few months I have been having a pain on my left side. This only happens when I am on my period. My mom tells me that it can be my ovary that swells up during my period. The pain is just like the one I had while I was recovering from my c-section. It hurts to get up and when I cough. This month the pain had gotten worse. I do not have insurance so it is not easy for me to go to the doctor. I went online to do some reading on this but now I am worried. Can this pain be from a cyst?
