Suggest Treatment For Severe Abdominal Pain During Menstruation

I have severe stomach pains due to gastrophalgia, I had my gallbladder removed in 2009 and ever since then nothing seems to help. It gets worse when I come on my cycle, I seen a gynecologist who suggested the depot provers shot to try and treat it, which didn't help, I just put on a lot of weight. I have tried zofran, tramadol, percocet, protonic along with many others. Instead of having to result in having a hysterectomy, would marinol help?
