emergency contraception
"I was pretty sure I wasn't going to become pregnant, but just to be sure, I took Plan B (I still spent an agonizing month waiting to see if I was right). I waited about 48 hours after intercourse to take it, because I was afraid of the side effects, and I had to work and give a presentation at school. I felt a bit 'off' and nauseated after taking it, but nothing serious. Don't let the side effects stop you from taking Plan B. It's pricey, but I think it's a good idea to have a dose on hand, just in case."
