I ended my last period on the 14th after a week. Nothing special. Three days later, I had sex. I've been sexually active for about the last 6 or so months. I can't get birth control, so my partner and I are relying solely on condoms. Unfortunately, the condom broke. We went out and bought some plan B, and everything was good. That is until today, a week later, I began to bleed. I thought it was just maybe a scratch after having some fun last night with my partner, but it's continued all day into a full period.
Is it common for this to happen after taking Plan B? I read a period could come sooner, but a two-three week break with barely any fertility window seems weird. Is this normal?
(P.S., I apologize for the poor grammar, I am typing this under a Christmas dinner table.)
