Help!!!!

How do you stop thinking about if your pregnant or not!?!? I feel myself everyday thinking about being pregnant but I haven't even ovulated this month yet (2-3more days). I can't stop over analyzing everything and hoping and crossing my fingers this month like I do every month. People keep saying don't think about it and just let it happen but its so hard!! 😩 I don't know how to help it out of my mind!
