Butterfly, so sad, thinking of you today 
Lynsey, don't feel bad for being self involved. Just getting through the days, however that's possible, is all anyone can expect right now! I also totally understand the feelings of potential resentment. It's all very well being positive - today I am pregnant, etc - but what if what that actually means is today I am sick as a dog, an emotional ruin etc etc. I really hope its all going to be worth it this time (for all of us!)
Tinkly, that sounds like quite the year. Well done for getting through it. I hope all goes well with your tests today.
Keys, sorry to hear you're uncomfortable but great to hear your little one is staying put for now. I hope people around you are making things as easy as possible for you.
Hey Lisa, welcome & congratulations. How old are your DC? It's funny you used the word 'failure', that is exactly how I felt too. The pregnancy which I lost was in an previous relationship, so explaining that to my partner has been hard. I'm 18 weeks now, and I've had to tell most people, although not work yet. I dread the un-telling if everything goes wrong now but it is good to not be keeping secrets from close friends and family anymore. I think there are good points on both sides, for secrecy and sharing. Do what's right for you. As for the shopping, I'm yet to buy anything. I've got my 20 week scan two weeks today, so if all is well, perhaps I'll start after that.
