When to See Doctor?

How quickly do you all go to see the doctor if you find a worrisome spot?
I will admit I’m a hypochondriac so I’m literally ready to go at the drop of a hat. I had one derm tell me to not look at my skin at all, to go to my regular doc once a month for a skin check and come to them every 3 months (more for state of mind than necessity).

I have a mole that I have had for years and I cannot pinpoint any real changes to size, color, etc but in the last few days I have convinced myself that it is worrisome. Sent my derm some pics (weekly instance for me) and he said it was reasonable to question the mole, but not to lose sleep over it, that could take care of it at my next appt. Plus my regular doc looked at it and said it didn’t appear worrisome, I’m still struggling not to see my derm ASAP to get some sort of confirmation about it and to get it off my body whether it is worrisome or not.

This is of course in addition to the dozen or so other spots that scare me on my body.
