emergency contraception
"The first time I took next choice I took it 3 days after unprotected sex and was afraid it wouldn't work but my period came as usual. The second time I took it 24hrs after unprotected sex my period didn't come as usual but thankfully right before I was about to waste $14 on a test my period came late (better then not at all). Next choice has always worked for me. And I wouldn't hesitate to use again if I had to."
