Should I just wait it out and see if he calls or text me?

We have been dating for 1 1/2 months now. This is the first time he missed a call from me and never called back or even said sorry I was busy and I couldn't answer that call. So nothing last night and I woke up this morning with nothing as well. Now I'm worried that something might be wrong or he isn't as interested anymore. I want to message him but I'm afraid I will come off as overly persistent and push him further away.

Sorry I forgot to update but he did message me back apologizing for making me worried and that he was with his cousin.
