emergency contraception
"I had unprotected sex and took Plan B less than 24 hours after. A week later, I began to bleed for three days and by the fourth it was a brownish color. Im not sure if this was caused by the plan B or it's my period because I got my last period July 9th. I recently got very sick, sore throat, cough, back pains, tender breasts. I also threw up this morning. I have a doctors appointment tomorrow and will see if this was caused from the plan B."
