Would I come across clingy if I text the guy I’m seeing if his ok as I haven’t heard from him in three days?

We was texting three days ago completely fine normal chit chat. And I then noticed he hadn’t opened my last response that I sent him on WhatsApp and he always opens my messages on there. When Iv looked I haven’t seen him come online on WhatsApp either which I have found strange as since Iv known him his always used WhatsApp. I did have a look to see if his active on Facebook and it keeps saying his online on there as it’s been coming up as green so he is alive and kicking. Am I being ghosted by him on WhatsApp? What should I do? It’s been three days now and I’m starting to get a bit upset. Should I give it a few more days then be like hey hope you’re well or something?
