Plan B

Emma • I'm an art nerd, and I'm in love with a history nerd.
My period was three days late and I shook it off as still being pubescent and hormonal. I had protected sex today and when he fished he went to finish in my stomach and his aim was awful and landed in my crotch so, I took plan B about 5 hours later. I've had cramps and that sharp pain in my ovary area and stuff. How much longer until I get my period again?
