Need some advise

I've hardly told anyone im pregnat apart from my boss & a really good friend.

I wanted to wait until my scan before i announced it to the world !

Problem is my friend has had 3 misscarridges, all before 12 weeks & I find she talks about my baby alot, asks lots of questions but then gets really upset because she just thinks about the ones shes lost & its really hard for her.

She's had help & is on depression because if it.

She dose have a 18 year old son but she finds anything baby related happy & upsetting at the same time.

I've asked her if she could come to my scan with me as my husband will be at work & I didn't really want to go by myself.

She's really excited about it but said be prepared for tears!

I know they'll be happy tears be I also don't want her to get really sad & go home & cry!

I'm not sure how to cope with it- it's a weird situation.

It's nice to have someone so involved & excited.. she's already told me she's brought me some things & keeps telling me I'm having a girl ( She's always wanted a girl )

She's already said she wants to make the cake for the baby shower & texts ke daily asking how baby is.

But I also feel I'm going to upset her & don't want too!

Am I doing the right thing In taking her to the scan & letting her be so involved?

For me it's nice to have someone to talk too as i don't really have many friends & the ones I do have i don't want to tell yet!

Once I tell my parents i know my mum will be mega involved but I also don't want to rule clare completely out as she dose refer to me as her daughter & I think she is enjoying the whole baby thing... but I dunno. It dose really upset her.

Anyone got any advice?
