Period 4 weeks pp?

hi all!

i’m only 4 weeks pp but i seem to have already started my period? i had basically stopped bleeding around like 2 weeks pp and even when i did it was very little and more pinkish blood. now, i’m bleeding a lot more (not a concerning amount of blood but definitely more than before) and the blood is bright red. i’m ebf, and everything i’ve read says if you are ebf your period wouldn’t start for a while. is it normal/ok for me to have seemingly started my period so soon?
