HORRIBLE MENSTRUAL CYCLES?

I am a 35 yr old mother of 4. After the birth of my twins 5 years ago, my periods and PMS has got so much worse. Sometimes they are only two weeks apart for 7 days. The longest span is 3 weeks in between. 3 days prior to, I am so fatigued I can't move. Last month I bought midol, took 2 and took a nap an hour later. Also, the pain doubles me over. The full cycle, from PMS (about 3 days) to after (severe cramping for 3 more days) lasts about 11 days every month. I want a hysterectomy but haven't built my case just yet. My hemoglobin is dropping. However, after my twins, I got MRSA in my c-section which makes me even less a candiate for a hysterectomy. What meds can the doctor give me to help? I DESPERATELY NEED SOMETHING and CAN NOT TAKE any kind of birth control. Every pill/shot has had an adverse reaction on me.
