Is this a sign of OCD?

Every cup I drink out I have to clean first incase of germs or whatever and same goes for knifes,forks,spoons.

I like things to line up straight.

I count things like I start tapping on the desk or something and then I will have a bad thought and say to myself that if I dont do the tapping another certain amount or times then something terrible will happen to me or someone I care about.

I have a fear or the number 3 and 13…if I have something 3 times then I have to get rid of one or something. I get scared that if I do something that ends with number 3 or 13 something bad will happen. I feel nervous even writing that number

if im looking at the clock/mobile or watch and the time is something ending with 3 or 13 if I blink when it is on that number I have a horrible feeling theres going to be something seriously wrong with me.

I think people are always talking about me.

Is there something wrong with me??
