"i had sex the day before i was due to ovulate. just my luck, the condom broke and he came inside me. i took plan b about an hour after the incident. the only side effects i experienced were light nausea and cramping. i was convinced it didn&#039;t work since i was so fertile at the time. i spent two weeks reading reviews like these and over-analyzing every little change in my body! a week and a half after i took the pill, i started experience brown discharge and was worried that it was implantation bleeding. thankfully today, three days later, af arrived right on time!!! i would say this pill is effective, but the paranoia that comes with waiting around for your next period is enough to drive you insane."
