Melanoma during sunburn?

i got a pretty severe sunburn last Wednesday and it looks as if it's about to peel, but just last night i noticed 3 small spots on my back, two on the right side and one slightly more noticable one on the left. It was an off color, almost my skin tone but leaning toward a scab or zit like color. they are not painful or itchy to the touch and they are hard like a scab, so i picked half of on and it looks as if it is localized to the top layer of skin. Should I wait for my skin to peel and if it is still there should I see a doctor? or am i just overreacting?
