Yes.: These questions can act as a screen for possible OCD: Do you wash or clean a lot? Do you check things a lot? Is there any thought that keeps bothering you that you would like to get rid of, but cannot? Do your daily activities take a long time to finish? Are you concerned about putting things in a special order, or are you upset by mess? More detailed assessment can be done by your doctor.

Evaluation: A good psychological evaluation will be able to provide an answer - I'm so glad you didn't say "know for sure". The more accurate and complete your descriptions of these things are, the better. Some OCD symptoms are harder to deal w/ than others and may really push you around. It's good to get this managed as well as possible and it can take patience and effort. But it's worth it! Best wishes!
