"my girlfriend and i had unprotected sex 11 days ago. i didn&#039;t cum inside of her but i was scared that pre-cum got inside her. she took the pill 49 hours after we had sex and we had to wait a long 9 days after taking the pill before she got her period. this pill will work for you, i promise. after taking plan b she experienced pregnancy like symptoms for the next few days. swollen breasts, lower back pain, severe cramping, hunger, sweet tooth, stomach pains. but it works, just give it time."
