Welcome to the newbies, and congratulations!! marmite there's a few older mums on here so you're in good company, some of who are first timers too.
Apprentice hopefully your DH is just letting off steam, however maybe this will be what spurs him on to finish sorting the business... My DH spent years plodding along at work with no ambition, once we had DS he wanted to work his way up to give us a better life as a family, but also he told me he wants DS to be proud of him and he's now pushing himself, working his way up, its been amazing to see :)
Gaw when you have your 12 week scan they give you a definite (well, as much as possible) due date. LMP is approximate but doesn't account for the date you ovulated, how long for implantation etc so once you've had your dating scan this becomes much more accurate.
Finally found something I can eat without it knocking me sick - chicken and sweetcorn soup! Can see I'm going to be living on the stuff for the next couple of weeks. Feeling very sick this morning again though
