"i&#039;d be lying if i said this was the first time i&#039;ve taken plan b due to a sexy time slip up.  in fact, it&#039;s the third. the first was 10 years ago (when it wasn&#039;t otc and 2 pills). the most recent was dec 18th, which, by the the was ovulation day, i didn&#039;t realize until after the fact. i took plan b maybe two hours afterwards.  over the weekend i was super fatigued and crampy as well.  the following week i felt fine.  my period was to come on new years eve, that monday the cramps started back up on tuesday i was spotting.  on nye my period started and ended on the 4th.  today, i noticed a little bit of spotting, but i&#039;ve had that happen before with plan b. so, not preggers and so is finally calling about a vasectomy."
