My periods are really irregular too. I wouldn't worry too much, but if you aren't wanting to get pregnant right now I would make sure that you are taking the proper precautions! I was worried too for the first seven months, but now I have accepted that my period is just a mystery! Some months it is light, others heavy and sometimes nonexistent! Give it a couple of days and if you still feel like you might be pregnant and you are worried get a blood test.
