Melanoma skin cancer? (Pic inserted)

I’m freaking out. I have a mole on my left thigh that sorta looks like it could be pre-cancerous or cancerous if it isn’t already. I’ve had it since I was a kid and have been watching it since then but I just now realized how it looks now... and it’s not good in my opinion. It seems to be different now. I read about the signs and what signs to look for in a mole. It’s smaller than a pencil’s eraser but its brown with darker brown dots on the inside and I could’ve sworn it wasn’t like that before. I can’t even call a dermatologist until Monday to see if I can get a biopsy done on it, so I will now spend the rest of the weekend and however long the results take to get back, stressing out about it. Help? Has anyone had something like this before and gotten it checked out? I’m so nervous, especially with the virus going on too 😞
