Continuously bleeding 3 weeks after colposcopy and biopsy

I attended my colposcopy 3 weeks ago and needed to have treatment for high grade cell changes. They also took a biopsy. 3 weeks later I am still bleeding (heavier than my normal period) and still passing clots, they started off large but now small ones. Is this normal? They said I was to expect bleeding but didn’t think it would be this heavy. I can feel it flowing out even when walking around
