Found a random mole on my left finger one day and after 4 days, it started to fade

[Bubbletea]

I saw a small, brown dot on my left palm (on my pinky finger) one day and I was like wtf this wasnt here before, and this one looks different to the rest of my moles but anyway I brushed it off afterwards. 3 days later, I looked at my finger and noticed that it is fading (picture shown) and I got curious/worried so I googled. I found out that it might be melanoma, but I need some reassurance
heres the mole when i first saw it


here's the mole 3 days later
