Is this normal? 8 weeks pregnant

So I was in the shower and I noticed that there are big spots of my skin that are lighter. It kinda looks like if I got a spray tan then touched it a ton and left finger prints but it’s my normal skin. It doesn’t hurt it’s just weird how there’s different colours. Is this normal? I’ve never heard of this before...
