Anyone else experience non stop bleeding

[Brizzle]

Has anyone else experienced a period bleeding for over a month?.
My periods have been all over the place since Jan. I hadn't had a period for 6 weeks before this bleeding.
Bleeding at ovulation, cycle length is different each month, stopping and starting, period length is longer and shorter and now this.
Had Transvaginal scan in April, which was normal.
I was put on Cerazette to help bleeding, but it hasn't.
Spoke to doctor, not concerned, have a gynae appt at sometime in the future.
Terrified its cancer. Bleeding seems to get redder and slightly more every week. I've started needing a pad now. Have at least 2 medium sized clots a day. Always red blood when wiping.
4 GPs not concerned, sonographer said uterus looked healthy.
