emergency contraception
"I had sex on Feb 21, 4 days before my period was due and his condom broke. I took Plan B One Step 15 minutes after the incident and I got my period right on Feb 24, right on time. I am not pregnant and I am 100 percent convinced that this is my period. I am bleeding right red, heavy blood with cramps (which is always normal for me on the first day). If you are ovulating during unprotected sex, the egg will be waiting for 24 hours until a sperm attaches. So do not wait, the sooner the better. I know Plan B claims that you can take it at 72 hours, however, if you take it within 15 minutes you are golden and you'll be okay. I experienced a headache and light spotting a day after taking Plan B. It can cause a little bleeding, don't be fooled!"
