emergency contraception
"My boyfriend and I had unprotected sex around 11:30 p.m. on 12/3, and I was due to ovulate on 12/5. He claimed that he completely pulled out before he ejaculated, but I wasn't completely convinced. The next day, around 7:30 p.m. (20 hours after the act) I took a Plan B One-Step. Since I was so early in my cycle, I knew I would have to wait a while to see if it worked. I did not experience any symptoms until about a week later, when I started having sore boobs, headaches, and light brown spotting that lasted a couple days. I was due for my period on 12/21 and it came a day early on 12/20. For everyone out there worrying: STOP! If you took it within the suggested time frame, it WILL work!! Relax and let the pill do its job :)"
