Hi Anon

Thanks for your post!

Every time you take emergency contraception, it works for one time only. So if you had sex on Friday (even several times) and took it on Saturday, it helps prevent you from getting pregnant from sex on Friday. If you have sex a couple of days later, the emergency contraception that you took on Saturday will not still be effective.

Does this answer your question?

To my knowledge it can still work but may not be quite as effective. Call your pharmacist for confirmation.
