Melanoma? Or just a normal spot?

Hello there, Since 16/9/2019 I had notice a very tiny spot (ballpen size spot) on the side of my finger. I already went to see two different doctor (General Physician) both of them tell me not to worry. I can't get a dermatologist appointment unless the GP refer me to. The spot is not raised, and black in color. What do you guys think? Here's the picture.

It is too tiny to either diagnose or worry about it being a Melanoma, My Melanoma was already raised jet,shiny black and large when I noticed it. Still waited 6 months before having it taken out. Before that I had noticed a red ring round the base of it which next day had already darkened and another red ring had formed - this is how it was growing. Also it had a secondary on top of itself called a satellite which I had thought was a little soft wart.
I once had a small hard black raised spot on my back so could not see it and GP was suspicious so referred me.
I had to laugh as it was indeed a blackhead and the specialist squeezed it out for me ! It was bigger than your pin prick sized spot. Keep an eye on it to see if it grows and changes but I doubt it.
Good luck
