Pain and excessive bleeding after tubal ligation

Mary
Please help cuz I'm not sure if this is normal or not. 6 Months ago I had an emergency cesarean (my 1st), and I also underwent a tubal ligation. My tubes were cut not burnt. Every period I've had after the birth have been extremely heavy (I bleed through everything; pads, underwear, & pants) and I'm in a lot pain. This excessive bleeding goes on for days if not my whole period. My 1st baby was delivered vaginally and my period went back to normal. With this one however it's completely different. Is that from the cesarean or the tubal ligation? Has anyone else had this problem?
