emergency contraception
"This thing really does work! I was expected to have my period on Friday and the condom broke Thursday. So needless to say I was paranoid. I took the pill within 30 minutes and felt instant cramps.  I read all these reviews and they put me to ease, but still felt the stress.  I got my period EXACTLY a week after the incident, but was still nervous because I was 6 days late from the expected period.  But please don't worry, it works.  Though the period is absolute hell and painful, I've never been more excited to have it."
