Black mole - center of my back

BACKGROUND ON MYSELF: I'm a 24 year old female...I'm really pale/light-skinned and have many freckles and moles all over my body. I've also had severe sunburns over my lifetime.

MY OBSERVATION: Just last night, I noticed a black mole in the center of my back that I've never seen before. It was bleeding as well, but before that I was kind of itchy so I had scratched my back. But I'm kind of nervous about it. I had my boyfriend look at it, since it was kind of difficult for me to see clearly and up close. He told me it was a dark brown, not quite black. And it doesn't have any rough/jagged edges. But it kind of hurts...not too bad, but I can definitely feel it...quite possible it was from scratching it, who knows. Yet I've never seen it up until last night. I DON'T HAVE MEDICAL INSURANCE. I LIVE IN VANCOUVER, WA. And I don't know where to go to get screened or have a doctor look at this. PLEASE HELP. THANKS.
