Plan b

2 days after my period ended I had sex but the condom ripped. I took plan b. Exactly one week after taking plan b I started bleeding. It was heavy - just like a period.

Did plan b make my period come early.?

Haven’t had sex since. There’s like a 0% chance I’m pregnant right???

Ps I’m supposed to start my period tomorrow. If I don’t start it should I be worried?
