Suggest Treatment For Septate Uterus With Excess Menstrual Bleeding

I am a 33 year old female with a sub septate uterus and experience heavy bleeding and severe menstrual pain before, during and after my cycle. The endometrial biopsy was negative and the colposcopy was showed benign. My tubes are tied- 11 years now. I have tried hormones, medications- No Depo because females in my family have had bad reactions. What treatment options do I have now. I will not rule out any option
