I'm 30 years old and 30 weeks pregnant with my first baby.

Today I am going for my very first appointment (at the GP but with a skin specialist?) to get a mole on my backside looked at.

Ive had it since I was a little girl, but because of where it is I don't see it regularly and forget it's there.

2 weeks ago I saw it in the mirror, it looks larger than I remember and up close photos show it has a few white spots, where before I'm sure it was just a round dark beauty spot looking thing. 
 

This fear at any time I'm sure is absolutely horrible.

But to be going through this when I'm due to have my baby in a couple of months is just.... I can't express that. 

Im terrified. I wish today will be a biopsy (maybe it will?) but I don't think so, I imagine it will be a referral for one and another long wait while my baby continues to grow. 
 

Does anyone here have experience of multiple white spots in a large flat mole that turned out to be nothing? 
 

I'm trying to keep calm as I know stress is bad for baby but how I am supposed to?

I'm scared. And I'm most scared that if it is bad news it will have affected her.

I've been awake since 5am. It's 7.30 now.

My appointment is at 11am.

Not how I imagined my pregnancy experience to be.

Any help is so appreciated. Thank you.
