I was watching TV today, like I usually do when I'm bored, and saw a commercial for a pregnancy test that's apparently more accurate and can give you results 5 days before your expected period...  what got me was when the lady said

"Imagine what it would be like to know your pregnant the moment it happens... science is getting closer..."

So I did imagine what that would be like... and really don't think it would be pleasant. What I can only imagine is some alarm going off, or the "ding" sound of an easy bake oven as soon as you're done fucking.  Well it can take up to 3 days for a sperm to fertilize an egg... just imagine that wake up?  Oh! And imagine the pranks... guy fucks a girl at a party who says she's got this device that goes off if she gets pregnant, only to wake her up with a similar sound during the night.

I don't think it's a good idea... I'll stick to worrying about it until my rag comes or is a couple weeks late.
