11po bleeding-AF or IB?

Ashlee

So me and the boyfriend did the deed 8dpo and I woke up on 9dpo with bleeding. Yes it was a tad rough but no big deal. I bled all day 9dpo and 10dpo with very mild cramping. 11dpo... nothing. No blood no cramps and no cm! I'm so confused and upset. Any advice would be great. Thanks.
