It's not OCD, and if it is it's an extremely mild case.
Everyone has ticks that make up who they are, there's no need to fear.
For the longest time I thought I had OCD, so we went to get me tested for it, and it turned out I had a mild case of OCD and depression. However, now two years later I am not diagnosed with either of those two.
tl;dr; Don't worry, it's probably just a phase/nothing
