See a dermatologist: what you describe dosent sound like a malignant melanoma which is your concern however its easy to have a term examine it. In all likelihood if its as you describe they will tell you nothing to worry about or do .Malignant melanomas are odd shaped , one half docent match the other, the color varies,. I would simply get it examined
