Should I text this girl?

So there’s this girl I like and I asked out to the movies this Friday, she said she didn’t have a ride so she couldn’t make it and I was like “Ight, maybe some other time then” and she said okay. Right now, I’m kinda impatient for the next time I see her in class, so should I was thinking about just texting her to say what’s up. If I do that, it’ll be obvious that I like her. Is that okay? Do girls mind when you just text them randomly like that? Or is that just for girlfriends and boyfriends?
P.s. I kno I sound like some middle schooler but I’m actually 18 😂 I just don’t have ANY experience in relationships 😂😂😂
