i used to have the same kind of periods you did. it looked like my liver was laying in the toilet i clotted so bad. i have a fibroid tumor on my uterus and that was the cause of it. so i had the choice of a hysterectomy or the pill even though like you my tubes are tied.so i chose the pill and am now on levlite for 2 yrs now with absolutely no problems from the pill and no more periods at all. i go from one pack of pills to the next without skipping a week and have no period. you might want to talk to your dr about it. i am no longer anemic either.
