The 24 hour engagement.

[ZenGum]

I don't have much else to say, being pretty hopeless at relationships and understanding women and such. But I say this: your heart is NOT an idiot, and you were right and wise to ask her if it felt right to you.
There is much, much more regret in the things you never dared try, than in the things you tried that didn't work.

FWIW, my guess is, give her a week, and then call her, see if she wants to talk, see how it goes. Just my guess, though, that's roughly driving advice from a guy riding the bus.
