I am 37yrs old, I had ovarian cysts when I was a teenager but they went away in my early 20's. Now all of a sudden in the last 3 months, when I have my period I have bouts of severe cramps with nausea and diarrhea. This morning I had a severe bout at 4am and the pain reminded me of my ovarian cysts when I was younger except this was much much worse. Could I be getting ovarian cysts again? Could it be something else?
