"i had unprotected sex a day after i finished my period. i am not on birth control so we used a condom. it ended up breaking and he finished inside of me. i ended up taking plan b as soon as i could &amp; a week later i started spotting then it turned into a light period for 3 days. after terrible head aches, back pain, breast hurting and a lot of worrying i got my period a week late. it does work so don&#039;t freak out! once you spot from the pill your period should come a month after that time. so just relax, you&#039;ll get it!"
