Dark spot on my albino cornsnake. Vet?

Hey there! I have a light colored cornsnake and I noticed that she has a dark spot on her body. Should I be concerned and take her to a vet?

I wish I could get a picture but it's underneath her belly and its hard to get a good shot. It's not part of her markings and seems to be inside of her.

I'd rather just be safe than sorry on this, but she's moving around fine and has eaten with no issues... so I'm not sure if I'm just being too worried for my own good.

Another question is that, how do I make my snake less scared of me? I feel like with every time I pick her up she gets more frightened and less likely to show up in the cage. I only have been picking her up 2-3 times a week.

Thanks so much!
