I am 6 months post partum, and exclusively breastfeeding so no periods. I also had a tubal ligation done. The past three or four days I'm having period like cramps, but no period. IDK what to think. I had fibroid tumors a couple months ago, but figured those had gone away by now? Should I contact my ob, or keep waiting it out? The cramps are like a 7-8 on a scale of 10, but they come and go. They aren't constant.
