"the pill works! my period ended on june 9th. days after on the 17th, i had unprotected sex and was not sure if my boyfriend had came in me or not. seven hours later i had bought the pill and drank it just in case.stupidly, on the 20th, i had sex again. this time my boyfriend had a condom on. but it broke and he came inside of me completely. i was freaking out cause i&#039;m only 17, and can&#039;t afford to be pregnant. but i bought the pill three hours later and drank it. some side effects i was experiencing was backaches, headaches, nausea, vaginal discharge and brown spotting. lucky to say i got my period today! at the expected time. thank you plan b! any side effects you experience ladies are all alike to pregnancy, just don&#039;t stress!."
