Thanks for your help. I looked it up also and it said that even if you take the second dose 24hrs after you took the first, it should still be effective. I took the EC like 3 hours after the incident.

That is great! EC can be taken up to 120 hours after unprotected sex (some EC is only up to 72 hours afterwards), so taking it only 3 hours afterwards highly increases the effectiveness.

Best wishes!

There are no guarantees when taking emergency contraception that it will be effective at preventing a pregnancy, even when using it correctly. EC has the highest success rate when the following things happen:
1. EC is taken immediately, or as soon as possible, after unprotected intercourse
2. EC is taken as directed

It depends how long after your unprotected intercourse (or birth control failure) that you took the first dose of EC. EC provides some extra protection against pregnancy (up to about 80%), and if you take the first or second dose late, it just decreases the "80%" effectiveness rate. The first dose is probably most important, if that helps?

When are you expecting your next period?
