My uterus has been "f'luttering" for a couple days now. I'm 43 years old, have excruciating periods and been having hot flashed for some years. My dr. just laughs when I mention the menopause word. My periods start out dark brown, then become FULL of clots. Period lasts about 7-9 days, with extreme back pain and what feel like cramps down into my butt/leg area. However, I am usually bothered by PMS symptom for a week before I even start. So for at least half the month I feel extremely lousy, and not much better for the other half. Based on other women's symptoms I've read online, I am thinking I have endometriosis. I think my dr. once told me that usually happened to "younger" women. Now this uterine fluttering has begun and added a whole new symptom for me to ponder over, but I know it is NOT gas. I have had 2 'normal' pelvic ultrasounds in the last 3 yrs. I have 2 children. Can anyone please tell me anything?
