Spotting years after a hysterectomy?

I’ve almost had my hysterectomy 5 years ago. I had everything but one ovary removed. I’ve done two ct scans for my left ovary as I’ve had pain and it’s clear no cysts. When I had my hysterectomy I had cysts everywhere and a huge mass off my right ovary. They thought it was cancer and two weeks after we learned it was just a huge cyst. Today when I used the bathroom I had spotting then heavier bleeding and spotting. Nothing since. No sex recently no injury I know of lol (no sex). So weird. Some people told me they had to have fixes? Is this normal or should I worry?!
