Should I message her again if I haven't heard from her today? Or should I wait to see if she eventually replies?

Basically I started messaging this girl yesterday and things were going great. I asked her if she would like to exchange contact info and she said "yesss" so I asked her if she preferred texting my number or Snapchat or something and she hasn't replied. I was thinking of texting her good morning today or something, but I don't wanna come off as desperate. What should I do?

Should I message her again if I haven't heard from her today? Or should I wait to see if she eventually replies?
