OCD or no OCD is irrelevant. The question is whether the overplanning and analyzing is causing a problem to your day to day life. If it is, then you'd need therapy/treatment. If not, then you don't need to bother. So you're the judge here. Check whether your productivity/ functionality and social life is getting hampered by this habit or not.

Hi. OCD has two parts to it; one obsession with some thought, feeling or object and second part is a compulsion which is undoing in form of an action, physical or mental. Over planning and overanalysing could be a part of your personality as well. If you say it started some time back.. Then an event where you acted without thinking or analysing leading to a bad consequence; may be a trigger. In either situations, if it bothers you kindly meet an expert to resolve it. Rest Goggle gives you more of a general view, every individual is different. It gives good information though. Take care.
