Do I have an OCD? What should I do?

I keep checking things like at work when I in/out on biometric scanner I check it 5 times to see if I got in or out on the biometric. And then I always ask the same question to my coworkers my coworkers think Im annoying. At home I keep checking my things thinking maybe it might be lost or someone might touch them or just changed their position I check if its still there or in order like I left them. My things should be in line. If I brush my hair I would count 1-10 if I messed up counting 1- 10 I would repeat it brushing again counting1-10 again. The spoons should be in proper order like I count it to see if it still there we have 6 teaspoons and I always check if its still 6. My towel when I put them should be in proper line folded on hanger same length of its end on the other. Im just angry cuz I think I have undiagnosed OCD and my coworkers are annoyed I keep asking the same question. Whats wrong with me? How to fix it? If I tell my coworkers I might have OCD do you think they would judge me? Im so embarassed and can't even tell them my illness because I work at hospital and Im worried they might judge me of being stupid for asking same question
