"i know its really scary thinking your pregnant when you know your not ready .. i&#039;m 16 my experience was terrifying to me . it happened when we noticed the condom broke, he didn&#039;t fully ejaculate in me but some slipped in as he pulled and thats when we noticed the condom was ripped. 4 hours later i was able to take a the plan b no side effects occurred. it was on friday 13th , then exactly one day before one week passed i got my period ! don&#039;t stress . taking the the pill works the sooner the better ."
