"i had unprotected sex (stupid i know) but he did pull out but i noticed i was in my ovulation days once i checked my app that tracks all of my periods and such. in all honestly i&#039;ve been successful with the withdrawal method but being so close to ovulation scared me (you know with the whole pre-cum debate) so i went out the next day and purchased a plan b and immediately took it about 18 hours later. i didn&#039;t feel any side effects right away but a week later i got my period! (which came a week early) don&#039;t know if i needed it but i&#039;d rather pay 40 dollars than risk it. :)"
