OCD, like I need another thing to worry about

I joke, a lot. Half of the crap that comes out of my mouth is just gibberish. So, when Blaine was like 1.5 yrs. old he would do these random things that had me asking myself "Is he OCD, or what?" I once and only once made that statement to my DH and he looked at me like I was a crazy lady, which sometime I am let's face it.
Well, long story short, last night DH comes DS after putting Blaine to bed for the 4th night in a row and says "I think Blaine has OCD" Okay, so picture my eyes wide and mouth drops to the floor and I say "Oh yea, why is that" He proceeds to tell me that for the past four nights that he has put him to bed Blaine has to turn in a circle, go over to the light and flip it three times, go back and circle and then get into bed. Okay, sounds ridiculous but it's true. The weird part is if he doesn't do it just right, he has to start over.
This my friends, is just one of the things he does. Another example: When he gives us a high five if he doesn't hit our hand "properly" he has to keep doing it until he feel the proper contact has been made, and if we don't he gets upset.
I have noticed that when other people besides Brian and I give him a high five, he does it but I can see he gets uncomfortable and weird about it. He also does things like walking by something and if one of his feet/legs touch an item, he has to touch the other one....UGH

So, should I take him to see the pediatrician or just wait it out? I don't want to freak out you know...
