"hi guys so on september 18(last day of my period) i had sex with my boyfriend, the condom got stucked in me and he already ejaculated.he didn&#039;t know until he asked me where the condom was. i freaked out. i found it inside me, took it out and then decided to useplan b. because from what i know, sperms can live up to 5 days and september 23rd was supposed to be my ovulation day. i took plan b 40mins later and after that i starting having headache,cramps but still i was stressed out. september 25th (my bday actually )before going to school i had cramps, i took advil because it was too much. next thing u know i got my period again (twice in a month). i feel relieved now and it actually worked for me .so girls just used it at the right time."
