What should I do about this situation?

Last night my husband and I had a fight..it was over nothing, I was cranky so I went to bed, he got angry, yelled at me for being in a huff and I just wanted some peace and some sleep. So of course I couldn't sleep and didn't want to fight, came downstairs to say sorry, but wasn't sure why I was apologizing which again angered him. Now we are in silent treatment mode and i hate, he left for work without saying a thing or kissing me goodbye. Why do we have stupid fights like this? Do all couples have these times? How do I fix it? This may be a dumb question but I just need some advice..thanks in advance for your input!
