"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&#039;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."
