Thanks everyone, I think I probably will text her, probably on a Friday after work then she has the weekend to process before we are back at work again on the Monday
I hope you are all right about her not being angry at me, I think that and her feeling like she has no one to talk to about what she is going through are the 2 main things bothering me (and of course her being upset - so 3!) It's just seeing how she reacted with her best friend and SIL - she was really angry and was very nasty behind their backs, and even now (they are both around 7 months pregnant) she is still very nasty about them
I'm going to tell her when I get to around 12 weeks before I tell anyone else (I'm 6wks+3 atm) - will let yous know how it goes
