Worried about a mole.

So this is what my mole look like before then many months I picked a mole by accident and that is what the second picture is of. The last picture is what it looks like now. It’s sort of a darker color in the middle but it doesn’t itch or bleed or hurt. I am just worried about the color. Does this look like skin cancer or melanoma? Also, I do not think the darker part is a scab.
