I have mole paranoia ever since a biopsy of a severely atypical mole. If I went to the dermatologist every time I found something "suspicious", I'd be there SEVEN days a week.
But, yes, it's good practice in general, to have a skin exam every year, and 6 months optimally. Your mole, however, does not sound concerning - at all.
One day, recently out of the blue, I became hyper focused on a small mole on my leg. I stared at it all day long with my iPhone flashlight, making many trips to the restroom, at work, to inspect. I could SWEAR that it was more raised, and darker, with darker spots coming out of it.
Strangely, now it seems fine and back to normal. I don't know if these things flare up, or if I get hypochondria-eyes.
