Messed up period pls help 😩

Alina

My last period I had for 4 weeks, yes I was bleeding for 4 weeks I went to the doctors I got a blood test and a ultrasound and the results were fine. I got my period again recently and it was normal and lasted for 5 days until tonight I’m begging to lightly bleed again! I’m worried about having cancer of the cervix or uterus!
