I'd suggest you wait first about 1 week or 2, keep picking up girls and if you do then do your stuff, if not then give her a quick text to see what's up.
Now before you do any of that, did you know the girl you've met ? Or did you just get to meet her quickly, because barely getting to know someone and then texting them, gets dull real quick unless they actually have interest in you. If they arn't interested, they won't care. If she would be interested in you she would be texting you. Thats why face to face interaction is the way to go.
