emergency contraception
"Okay, so I got back together with my boyfriend after 6 months apart...one thing led to another which led to us being together with no condom.  I was definitely fertile as it was right in the "window".  He wasn't worried about it, but I was freaking out, but didn't get to use the pill until like 36 hours after having sex several times.

Now, let me first say that the pill DID work after A LOT of stressing.  I had a forced period about a week after taking it, but then nothing for about a month and a half.  Considering side effects, I would have been better off just taking my chances.  I've had everything from pimples to nausea to cramps...to gaining like 5 pounds. Now I'm in the middle of the worst period EVER!   So it worked, but NEVER AGAIN!"
