"the day after my period ended, i had a little incident with my boyfriend penetrating me (without protection) for only about a couple seconds, before realizing &quot;hey that probably wasn&#039;t a good idea!&quot;. me being me, i freaked out and asked him to buy me the pill 12-13 hours later incase there was any cum. i didn&#039;t seem to get much symptoms the first couple of days, only minor cramping, yet i did go off on my boyfriend a few times due to terrible mood swings. my period was set to come in 3 weeks, and here i am, just got my period today! it was 3 days late, but it was all worth it. if you&#039;re reading this like i was before, you will be fine! my incident may have been fine without the pill, but it does ease your mind just in case :)"
