"i definitely want to share my experience...it seems i&#039;m one of the few who didn&#039;t have any negative side effects from it.  had sex on 7/22 and the condom broke.  took plan b about 8 hours later and spent the next week freaking out that i may be pregnant.  my period runs like clockwork, but i&#039;ve never really paid attention to when i&#039;m ovulating, but i estimated that i may have ovulated the day before i had sex.  like i said, i had no side effects.  i lost my appetite, but i&#039;m attributing that to the severe anxiety i was experiencing.  i was due for my period on 7/31, and started bleeding fairly heavily a few hours ago, so a few days early.  just because the side effects aren&#039;t there doesn&#039;t mean the pill isn&#039;t working."
