Is this me being OCD? Or something else

So i dont really feel the need to clean alot. Im not germaphobic either but i do have this thing where i need to do things a certain way. Like whatever i am doing i always feel the need to count to 3. Whether its blinking, or even taking 3 second breather. Everything i do, i do it 3 times but its not bad to the point where people notice. I usually do it in my head. And ontop of that, i always feel need to ask a question a certain way. And i keep asking it until i feel satisfied with the way i asked. i am an overthinker so it makes it worse. I always ask the same question too sometimes to be extra sure and whenever im not ill ask again cause ill tell myself “what if he didnt answer it the way i wanted it to be answered?” I dont understand what is wrong with me. I get anxious alot due to the overthinking so i shake my leg really bad and i have have to bite the skin from my fingernails and tounge and cheek. I need help
