Hey y’all

About a month ago, (I’m on the Sunday of the third row on my BC) I got off my IUD and started back on the pill that Sunday, (my period started on the 16th). My period lasted 3 days, 2 spotting days before)

I haven’t missed a single pill, but my period spotting started again on the 27th. Spotting lasted two days, but continuous regular flow hasn’t stopped.

My entire menstruated (??) life, my periods have only been for 3 days. I started out not being on the pill, started the pill to kill the cramps in high school, and then last year (21) got on the IUD. Do y’all have any idea what could be causing this long of a period when it’s normally never more that 3
