SO i have these horrible cramps in my lower back and I went to use the bathroom and a big clot, between nickle and quarter sized, came off of the tissue..and i was wearing a regular tampon. This happens every time so i just wonder if that s normal or not. Also, i cant seem to stop gaining or lose weight since i had my baby 3 years ago, no matter how much I exercise or eat right, so i want to know if the two might be connected
