Late Period

Madison

Hello Ladies, I’m currently 11 days late, here is a little back story. My ex boyfriend and I had unprotected sex 1 week before my predicted ovulation window, he finished inside. So here I am now, 11 days late, Monday I’ll be two weeks late. I’ve taken a few tests all come out negative. I’m now having light brown spotting, and light pink spotting, no cramping or anything and it’s not enough to be on a pad. So my question how likely is it I’m pregnant? Has anyone went through this also?
