Do I have OCD?

Im 13 and I think I have OCD. I dno if I have. But I have to do things with certain digits like 4, 7, 11, or 21. Or numbers ending with the number 7. When Im typing I often have to do two spaces after a fullstop then delete 1. Turning the lights on and off with those number. I hav to hit the whole key with 1 finger nd its not allowed to go over the edge.Whn I put things dwn I have to put them in a certain position bt I have to do it in a certain way. I have to touch corners with mi whole finger. And stuff like when I rest mi laptop on mi lap, and its partially touching mi leg I have to have mi leg totally touch it then take it off. When I hold things mi whole finger has to touch it. I have to touch things to too and corners. And when I put things down or sit down I have to sit down and stand up for or seven tyms. AND when i push thing or open them I have to open it it fully n slam it. Its not like i feel though sumits going to happen I jst feel better when I do and get fustrated.
