emergency contraception
"I took Plan B after a condom failure -- 10 days after my last period had started. I took the pill 5 hours after sex. I didn't have any immediate symptoms. After a few days my breasts became sore and I had some cramping. The cramping felt a lot like my ovulation pain and I started discharging egg-white-like cervical fluid. I was unsure if the fluid was due to the hormones in the pill, or if I had ovulated before taking the pill or despite taking the pill, so I was a little concerned, but tried to remain confident that I had taken the pill in time to stop ovulation. My breasts remained sore until got my period, on time, a little over 2 weeks later."
