Heavy bleeding every day

I have had a heavy bleed every day for the last two weeks. It stops for maybe 8-10 hours at night and then starts again the next day. Before the past two weeks I was bleeding once every other week, this has been going on for the last two months. I have seen my doctor and they did an ultrasound and said I have a fibroid but they said it has nothing to do with my bleeding. I am really concerned that something is wrong. Has anyone experienced this?

Also, I have slight PCOS
