prolonged menstrual bleeding

Hey...I have had irregular periods since December of 2018 and when I went to the doctor because I was bleeding for 2 months straight they put me on the birth control pill. I have stopped taking the pill a few months ago and my cycle was regular until June because I did not have a period. Then in July my cycle was normal again but then after my period ended I was spotting until August 15 when my next period actually started. I have now been on my period for over 2 months it is now October and I’m still on the same period from August. I need help because I have had blood work and it has all been good but I do not want to go back on the pill. Has this happened to anyone else????
