Ladies I'm worried help

This is my calendar this month when I started AF it was light the 10-11 then got really heavy for 12,13,14,15 then I thought it stopped that night but I was bleeding all wkend the only days I didn't bleed were 19,20 I'm still bleeding now and basically had bleeding 11 of 13days so far and I only had very mild cramps this whole time I googled some stuff and I'm scared has this happened to anyone?
