Did I go wrong? or would it seem desperate to try again?

[Jonathon]

There's this one girl in my class who I've kept my eye out for for while now but I never really racked up the nerves to talk to her. Finally as finals started rolling around I set my goal to get her number so I started making small chat with her and eventually got her number. I got it because everyone was leaving school and I saw her by her locker and went up to her, started a conversation and when we both started to go our separate ways I asked her for it and she gave it to me what seemed happily. So I waited about a day and I finally texted her. Her and I both have iPhones so I saw she read my text message. I also know she wasn't busy that night cuz she posted on Instagram that she was just sitting at home. Did I go wrong somewhere? and would it seem desperate if I tried texting her again in a couple of days? sorry about this guys cuz I know high school crushes should be the least of my worries but I just want to know what I did wrong or if I should try again. Thank you!

Be cautious you could come off seeming desperate or needy, but I wouldn't give up just because you didn't get the response you wanted the first time

The bottom line is if she wanted to respond she would have.
