The best thing to do right now is to stop trying to contact him. Let him come to you instead.
Fights will happen in any relationship-its a given. What you need to do is be able to work through these problem and grow stronger afterwards. I'm glad that you are willing to talk to him about this, communication is key in a relationship. It sounds like he isn't ready to discuss it yet, so that's why you should let him come to you instead. Its better than making the situation worse by bothering him when he wants to be left alone.
Distract yourself with things you enjoy. Spending time with friends and family can help as well. As does exercise- maybe go for a long walk?
Most importantly, don't stress yourself too much about this. He just needs some time to cool off; nobody stays mad forever.
