hello...last year I had a cyst on my fallopian tube the size of a golf ball. I didn't have surgery but instead I stay in the hospital 4 days so that it could be shrunk from some kind of medication that was given to me in an IV. I've always had irregular menstrual cycles. I've been trying to have a baby but for some reason I just can't get pregnant. Is it something more serious I should be concerned about?
