Hi My Name Is Sara, And I Had Surgery To

Hi my name is Sara, and I had surgery to remove a cyst that was on my right fallopian tube almost 2 years ago. Durning surgery the cyst was to imbedded in my tube. They ended up removing it but left my ovary. Each month when I get my period, I have horrible pain where my tube was. My gynecologist also removed about 6 polyps. I bled for about 3 weeks. I have always had heavy periods and horrible cramps. Is this normal?
