abnormal uterine bleeding
"Used to use Depo- provera for years. Then went through 3 yrs no period. It then came back with a VENGENCE. Had abnormally high amount of bleeding for 7-9 days with such severe cramping that it would often result in a missed day or 2 of work each month for months on end before talking to my Dr. Shortly thereafter, I  eventually got an endometrial biopsy. I was told the endometrial tissue was "hormonally confused"- was then put on Lo Loestrin FE. I noticed a huge amount of positive difference within first month & still  presently. Light bleeding & minimal cramping for 3 days- it's like night & day. I would highly recommend."
