concerned for friend and unborn baby

I've been struggling with this for a while now and don't know what to do. I've got a great friend with addisons disease (a rare disorder that affect the adrenal glads) and she's expecting her first baby in December. I couldn't be happier for her. She's a wonderful person and will be a great mum. But I can't shake this worry that something might happen to her or the baby that could cause her to lose it. Her condition means it's a high risk pregnancy. I'm don't like even typing it because it feels like I'm tempting fate. I know she has great medical care and has a doctor's appointment nearly every week with one of her 3 doctors.
A couple of weeks ago her drs said every thing was fine but she needed to stop work. One good thing is the placenta is actually making some of the hormones or what ever the adrenal glads normally do so she was able to cut way back on her meds. If anything happened i think it would be physically and emotionally devastating for anyone but her condition makes any trauma harder to recover from. This baby was planned and I'm sure she is well aware of the possible complications.
I don't know if i should talk to her about my concerns or just keep it to myself. You here about things happening and every time I do I get all worried again.

Thanks S.C your right. Other friends I've know that have had babies were stressed enough with out everybody else sharing. some women seem to enjoy sharing their birthing horror stories with any mother to be. I'm hoping to go visit soon if she's up to it. :)

That is wonderful news! I hope that she and the baby continue to do well. Give her our best wishes!

Thanks for the update.:)
