I am on birth control after having severe depression during my period. I had a tubal ligation done in feb 2013. All of a sudden I have been spotting the week before my period. My period is a lot heavier now after my second child then it has ever been. This month I had the spotting, my period, a few days break, and now Im bleeding again. So off and on for three weeks I have been bleeding, tired, loss of appetite, and irritable. What is going on? Should I be taking a pregnancy test? Is this normal?
