So my bf and I had unprotected sex on Friday. My period is supposed to start in 3 days according to the app but I'm VERY inconsistent.

Anyway! I'm not on the pill (I don't need a lecture on how stupid I am... I know..) but he use to be an alcoholic and a drug addict and he still smokes.

He pulled out and I know that's not a type of birth control, I just want to give all the factors.

My friends keep saying I'm probably just going to be late because I'm stressed not because I'm pregnant,

Just asking opinions?
