Mole on neck/down below

Hi,

I'm 22, female and had a large mole on my back which had grown to 11mm down and 9mm across turned black and red around the outside with grey in the middle along with blurred edges. I had this mole removed around a week and a half ago and am awaiting the biopsy results. In the meantime I found a mole down below which I always remember as being as small as freckle, this has grown extremely large and when the nurse took pictures to send off for my referral showed me and it again blurred edges black and white/grey. I stupidly used to hammer sunbeds and worshipped the sun up until discovering the mole on my back had changed. I have obviously been googling things as you do and feel like I just need to share to get it off my chest as I am terrified wondered if anyone had similar experiences?

thank you
