Having had my share of basal, squamous, and melanoma, I am a bit proponent of getting anything concerning being checked out by at least your primary doctor if not a dermatologist. Better safe than sorry always is a good rule to go by when it comes to your health.
First, the disclaimer: No one can give you a certain answer over the internet. Skin conditions need to be evaluated first-hand by a medical professional for an accurate diagnosis.
With that said - is this a new mole, or has it recently started changing in size, color, or shape? If so, those are signs that you should have a professional evaluation. If it's maintained the same appearance for years, then it is likely nothing to worry about.

It does have some irregular coloring and shape, so probably a good idea to have a doc look at it. It doesn't look like anything to lose sleep over. My sister is a nurse, and is fair-skinned and gets moles a lot, and her motto has always been, "when in doubt, cut it out." It's not usually a bad procedure, and can give you peace of mind. But again, visiting a doctor is a great next step for you.
