Gave a girl my number, she hasn't contacted me?

ManWithoutaFace
I have a crush on a beautiful deaf girl in my university math class, so I wrote her a note explaining that I would love to get to know her (and invited her for a drink) and that I'm trying to learn sign language. I also left my number in it. I gathered my courage and walked up to her and handed her the note. She seemed flattered/pleased while interacting with her.

Should I be worried that she hasn't texted me for over 24 hours after handing her the note?

I don't get hurt easily. My brain is starting to go into "moving on" mode. I'm just curious if any other girl who was interested would've contacted a guy after getting their number.
