It's amazing what a wealth of wisdom there is among my fellow mumsnetters, thank you all so much for your kind and well-thought out words.
littlehalo you are so right, there's no point getting myself wound up about it just now, I'll give it time and that way I give my friends a chance to show their true metal, its very early days yet. No, eskino she didn't even say "are you ok? (and I'm not, but I will be) but maybe, as beertricks pointed out, she is embarrassed as well as some of my other friends. Bunbaker's right too and fieldfare*, I can't make permanent judgements about my friends based on their reactions because it really is awkward to know what to do for the best I suppose, say nothing and upset someone or say something and still risk upsetting someone.
marrow that was lovely of your sil, it doesnt matter how many weeks you are when you lose, that little bean is still a baby to you and it feels so important to me that my friends understand that.
mammykaz she didn't offer anything, she didn't even text, I had to ask her to babysit out of necessity
, but you're right, I'll leave things just now and if it still upsets me later down the line then maybe I'll say something. bakingtins talking about it does upset me but I feel that its a good kind of upset, its a way of acknowledging and dealing with my sadness, although I know that we all deal with things differently. I don't want to pretend normality yet, I need to deal with the fact that it has happened, at the moment I feel kind of detached from myself.
welovegrapes your un MN hugs are very much appreciated 
I hope that my experiences will make me into a more sympathetic friend, although hopefully none of my rl friends will go through this themselves.
