Okay I'm caught up now 
Welcome to the new ones I hope you have a happy and healthy pregnancy! (there's a Googledoc on page 2 of this thread)
@TwittleBee I'm pleased you are feeling okay now. How funny that your MIL could be scanning you!
@Laburna remind me why you're not eating pasta? Are you low carbing? Although just realised that might be a silly question as cheese sauce has flour in! BTW I LOVE cauliflower cheese!
Lots of you talking about bouldering which I've never heard of
@HchyScott I keep getting paranoid about the boob thing too. Everyone here is sayng their really hurt and are growing loads and I'm over her poking mine in the hope I get some pain (sometimes they feel kind of bruised). I think they have grown slighty but not so anyone would really notice.
@Rose68 I don't know about th eNHS guidlines but my sonographer didn't seem concerned with my measurements and our foetal pole was pretty much the same as yours at 6+3 on Saturday (3.6mm). Baby was visible but no heartbeat detected yet. He said baby should be at least 7mm before a heartbeat can be seen. So that would be 7 weeks, right?
I'm going to call the US dept today and take up their offer of an 8 week scan - which I had refused, seeing as I was having a scan on Saturday at what I thought was 7 weeks.
Re telling people, I am just getting on with it. I'm not going to make any big announcements, but I'm not keeping it a secret at all. People can just find out. I've told my mum and she has told people (with my permission). DP has told some of his family - his brother and sister. But he is more nervous about telling people. The way I see it is things go wrong at any stage of pregnancy. I said to DP, when is a good time to tell people then? At 12 weeks? 20 weeks? At the birth? when they're 5 years old? There just isn't a 'safe' time to tell people. So sod it! 
Besides, my belly is too big to hide and I don't want people thinking I've suddenly got fat for no reason.
I hope everyone has a lovely day, despite the crappy weather!
