Changes in freckles/beauty marks

Not sure if this is the right group or not! But, Has anyone ever experienced changes in your freckles or beauty marks when pregnant? Or had new tiny ones show up? And anywhere on your body?

Idk if I'm pregnant or not (it's highly likely I'm waiting to test) but I've noticed my beauty marks are darker than normal and even had a few tiny ones show.

I dont want to freak and think its skin cancer (my arms and legs havent seen sun in months).
