This is nothing to get worried about.
Your mole is not a risk.
You have to observe for signs in a mole which are defined by the acronym ABCDE.
A is for Asymmetry: One half of a mole or birthmark does not match the other - yours is symmetrical.
B is for Border: The edges are irregular, ragged, notched, or blurred - your borders are smooth.
C is for Color: The color is not the same all over and may include different shades of brown or black, or sometimes with patches of pink, red, white, or blue - cplor is uniform in this mole.
D is for Diameter: The spot is larger than 6 millimeters across (about ¼ inch – the size of a pencil eraser), although melanomas can sometimes be smaller than this - it is less than 6 mm.
E is for Evolving: The mole is changing in size, shape, or color - as you have noted the mole appears to be changing. This is the only criteria that requires observation.
Your mole is quite safe. You should keep it under observation though. But dont get obsessed about it, moles are very common as you have probably observed and only very rarely do they pose a risk.
You can also show this to your doctor at your next appointment for your reassurance.
