Oh whinge away! that's what we're here for :) You're around 16 weeks aren't you which I guess means you're just in a waiting and growing bubba stage, rather than scans and appointments? I guess like you say there's probably not much to say between each time you see people! People (other than us) really don't want to hear us give a proper answer when they ask 'how are you?' They just want to hear "yeah, really excited, can't wait, loving it, etc etc" rather than "petrified, can't sleep, have nightmares I'll MC, can't stop thinking this might be my last chance for a child etc etc" - might be different thoughts for you, but these are mine, so I smile, I tell them everything's great, so excited and then come on here, read or write, and feel reassured this is a normal feeling for me!
People expect us to be sooo happy that it worked that all the negative feelings and memories of infertility, just wash away and we're floating about on cloud nine for 9 months! It's not their fault, this is something you can never understand until you've been through it! My friend had ivf a few years ago and I think I probably thought the same, that she was on cloud nine, but now I know, as she'll tell me now that I understand more, that she was petrified the whole way through!
Sorry you don't feel you have someone to talk to, I have a few people around, but still don't feel able to say how scared I am to them and talk to them!! Whereabouts in the country are you (don't need to say exact, just north, south etc?), is there any local groups where you can meet up with anyone, or anyone else on here near you who might want to meet up for a cuppa?! If you're near me (south/east ish!), I'll happily meet up for a moan and a cuppa!
