Thanks everyone! I'm 6+1 and managed to get stressed out within hours of the scan as they said baby measured 2mm, which a quick google search suggested might be a bit small. Have smacked myself with a kipper though and will go with the mantra "today I am pregnant" 
Thanks squizita for the heparin info - how did you find it in the end - did you get used to doing it? I'm not looking forward to it but I know I'll be like you and be anxious about stopping too...
Fedup that sounds like the last thing you need, hope DH does a good job dealing with it all so that you don't have to stress about it. I remember reading something though about how stress really doesn't affect babies that much - think about all the babies born healthy in war zones, etc! So its more just that it feels horrible for you than it does any harm.
Blank lol at nosebleed excitement! Otherwise lack of symptoms is fine, you're about the enter your "blooming" 2nd tri after all! I had a tiny bout of morning sickness yesterday and would be happy for that not to continue, I hate feeling sick! At the time it was quite a relief though (was literally an hour before the scan!)
tannyloo injecting in a tent - the glamours of pregnancy! We're visiting family for the next couple of weekends and I'm not sure what they'll make of me having syringes and a sharps box with me!
Congrats on scan ilove and great you don't have to wait long for the next one. And welcome Hough - love that I'm moving up the due dates list (which I will actually add myself to after the next scan, lol)
Have a great day all!
