Period late after Plan B

Andrea

Took plan B to be safe after unprotected sex (even if he never came) we were too drunk —my period came around the time it should have and it was a full period (heavy) but now a month later my period is a bit late??

Is this normal? I know I’ve heard plan b is a HUGE hormone dose and it can disrupt your cycle

anyone have experience with this?? I’m trying not to freak out
