File under "modern problems" - Modern women surprised to discover that sex leads to pregnancy despite contraception...

and while engaged in a "threesome."

From Dear Wendy:

A few of weeks ago I had a threesome with a couple I’m friends with. We are all 20 years old and for the guy’s birthday we gave him a threesome. I took the morning after pill when I woke up but I guess it didn’t work because I just found out that I’m pregnant. I know that I’m going to get an abortion but should I tell the father? I don’t want this to ruin his relationship or make things bad between any of us. What do I do? I am very scared of what this will do to all of our friendships. — Terrified and Pregnant

The answer suggests itself.

*Sheesh* - we are so screwed as a nation.
