"i took a plan b three days after my boyfriend came in me three times coming to find out on my most fertile day, a day after my ovulation day! i was scared it wasn&#039;t going to work, because i took it on the third day, my most fertile day, &amp; after he came in me.. three times! i had a lot of side effects and was 8 days late on my period! i just knew i was pregnant, the day i did start i did nothing but fit the criteria of implantation blood. needless to say i started my period, i&#039;m fine and not pregnant! it&#039;s works ladies!"
