I have always had heavy periods, but this month I have been passing large amounts if blood, huge clots, and have felt overall fatigued and a little light headed. I am cramping up pretty bad and have a lower back ache. I have used the softcup and when taking it out today I thought I hurt my cervix and that is why I am bleeding so much. Any advice? I'm not pregnant and have been on the same birth control pill for 4 years.
