bleeding

i’m 9 weeks pp and i got my first period at almost exactly 4 weeks pp and then i got it this months and it’s been like almost 2 weeks but it comes and goes...it started off heavy and then slowed down and stopped so i thought it was done but then out of nowhere it started back up and got heavy again and now it’s like pink and ive been having cramps and some back pain.. anyone else have super long periods after birth? is it normal? i was gonna mention it to my doctor the other day but i couldn’t go bc of the snow. i’m also on the pill idk if that makes a difference
