ok some times when I am doing anything like watching a tv show or playing a game or doing other stuff I seem to focus on a word or a phrase and spell it out in my head while moving my head like the letters would be writen like if I get the word 'hot' in my head I would go H move my head in the form of a H, O move my head in the form of an O and so on. do you think this could be a small sign that I could have OCD? if it does mean I could have OCD what should I do about it?

thanks guys hope you can help
