When should I text or call her?

I went out with a girl for the first time a couple days ago. I brought her to a mountain to teach her how to snowboard and she bumped her knee during it and it was bothering her. She also asked me if I wanted to go out with her and her friends to a club afterward. The next day I texted her to see if her knee was ok, and that turned into an hour long conversation about random stuff. Now it's the second day after the date and I'm wondering if I should text her today or give her a little time. We didn't declare the snowboarding thing as a date when we went, she just wanted to learn, but I'm interested in her now. We only met a couple weeks ago, and that was the first time we spent time together outside of a uni club we're in. What should I do? I'm so bad at this stuff lol
