Does anybody know if this is OCD?

I have a weird obsession with the number 14. And 7. Sometimes when Im tapping something, Ill tap it 7 times, then 5, then 3, then 1, then 5, then 3, then 1, then 3, then 1, then 1. If you can follow that pattern lol. Sometimes, I do that when Im walking, on the sidewalk, Ill step in on each block thingy in that pattern. Ive been weird with numbers kind of like this since I was little, I remember counting whenever I ran up the stairs. But I do it, every single day, or something to do with it. And sometimes when Im eating candy Ill have to have 4, or 7, and certain numbers that I like, I dont know why. If my friend gave me 3 of something, lots of times I would take another one to equal 4. There's a couple other weird things I do, but they are really hard to explain so Ill leave them out. Lol sorry if I sound like a psychopath, btw Im 14.
