"me and my boyfriend had protected sex on april 15th. unfortunately, the condom broke. i took plan b one-step about 20-30 minutes later (the sooner you take it the better it works). my period was due in another week, so the anxiety began. i was very sleepy and sick to my stomach for about 6 days but i just got my period! i&#039;ve never been so happy. if you took the pill within a 24 hour time frame you have nothing to worry about. stress will cause your period to delay even more. just relax, you&#039;ll be okay. this pill is very effective. accidents happen, and that&#039;s okay. plan b is only for emergency use though. i am so glad women have the option to this."
