Yep! The morning after pill should be taken at the latest 72 hours (or is it 48?) after an intercourse. There is another method of chemical abortion called RU 486 that takes the place of the progesterone hormon and therefore it can't function correctly which causes a period (in other words an abortion if there is an embrion there). But that can only be done at a hospital by a specialist and it's an official form of abortion.

That said, I don't want to encourage people to abort so I really hope your gf isn't pregnant. Even if she is, abortion isn't the only solution. But Shh! does have a point with her second paragraph.

Best of luck!
