His and Her Health

Hi,
I am a married 29year old mother of 2kids under age 3. I have always had issues with my menstral cycle (starting at puberty). I am irregular (I will jump onto anyone's cycle, just as long as I am around a female menstrating and I get cramps ssssoooo bad. I vomit from the pain (I vomited so hard recently, I pulled my pulmenary muscle) and I am incopasitated for at least 2days. My OB/GYN has tried several types of birth control. Some w/ high hormones and some with low. The "pill" did not help my cramps and only made it so that I knew exactly when I would get my period. So, I could predict once a month I will be held-up for at least 2days. I tried IUD, and after a month, my body rejected it and pushed it out (on 3 different occassions). I tried the depo shot, and found it messed me up "mentally," for some reason, I was like a crazy person on it. So, now I am for a loss. I do not know what I should do at this point. I do not believe it is right to have to deal with this as often as I do. Since, I have already had my kids, I feel like maybe I should get a historectomy. Does ANYONE have any ideas on what I should do? What are the benefits vs. the risks for this procedure? And, would it be worth it for me? Right now, I feel that having the procedure will improve my life. I will not have pain... Any ideas on what I should do??? PLEASE HELP??? :confused:
