Really concerned

I just found out that I’m 6 weeks pregnant. I’m incredibly excited however I’ve had these incredibly weird and suspicious moles over my body. This one is now elevated, red around the outside, black and it bled today because I couldn’t help but itch it was so itchy. As a nurse I know these are all signs of skin cancer but I just need some opinions on if you guys think this is normal or if I’m over reacting? Or should I see a doctor? :(
