emergency contraception
"So I had unprotected sex with my guy on Sep 15th and took Plan B within an hour or so. The next few days I had spotting, tender breasts, felt awfully nauseous and tired. Today's the 23rd and I got my period. It is a day early and a bit lighter, but I am glad it is here. The pill works though I am going to go on regular birth control pills so that I never experience this stress again."
