Okay, so for the past few months my period has been off, one month it'll start the 14th the next the 24th then the 18th, I have my tubes tied, and my period have been regular since then, except the past few months, I've had horrible cramps, (looks like a murder scene in the bathroom) large clots and multiple at a time, my periods have been lasting about 8-11 days. Does anyone have any suggestions?
