3 days gone after the sex. Can any pills be used to avoid the pregnancy now?

Ah buyer's remorse huh? Felt good at the time but now the prospects of creating a life is a little scary?

100% full proof way to not get someone pregnant is not having sex. But if you must don't say no to Mr. Condom.

Are you male or female? Where are you in the world? For a guy very little can be done if you had unprotected sex. So are you male or female?

No, there is no pills after 3 days. Sorry, first you do not even know if you are pregnant, now you have to wait and see if pregnancy happens
