Should I block him?

I've been with this new guy for almost a month. Today is the first day I haven’t heard from him throughout the day. He texted me at 5:50 in the morning saying that he had just gotten off work and he would be sleep all day. Which I didn’t think too much of but like who really sleeps all day after that. It seems like he is trying to set up an excuse for whatever reason. We have been consistently texting and being with each other up until today. I don't know what happened or what is going on but it feels like I’m being ghosted or something I don't know. Should I just block him?
