Hormone issue caused by tubal ligation

I had a tubal ligation in June after the birth of my son. Since then I've had nothing but issues. VERY heavy bleeding lasting 10-14 days for my periods ( soaking a tampon every hour and a half) insomnia, serious emotional issues (PPD has been taken care of) no appetite, hot and cold flashes, and serious pain and almost like IBS symptoms. Has anyone else had any issues following a tubal? My doctor thinks that it may be the cause
