"i had unprotected sex on july 3rd and my partner and i used the pull out method. he didn&#039;t know if he pulled out quick enough so i knew i could be in deep trouble. i took plan b 16 hours after the incident. from my period tracker that i have on my phone i was said to be ovulating on that day. i have been worried sick ever since i took the pill because it&#039;s said not to work during ovulation/post ovulation. fortunately, i got my period today, july 12th. it was a few days early so it did mess up my cycle a bit. i also had some side effects like cramping and fatigue. i am so relieved and i can say that this pill works for sure. just try to calm yourself the best you can and wait for your period."
