Congratulations LCR!!! Happy news, indeed, and I'm so pleased for you. Know just what you mean about not being able to stop grinning. I took a photo of my scan printout to send to my folks and found myself sitting in the office staring at it with a silly smile on my face. Enjoy it!
Welcome calibee - sorry you're here but hope you find a lot of support for the ttc stage and beyond.
Thinking of you pixie, and so sorry you found yourself grieving again on a previous EDD. 
Hoping for the best for you, notsoold (and sorry to you and to redbird for getting your name wrong above!). The waiting is awful, there's no way around it, but I hope yours ends happily.
As for me, I've buckled under post 16-week scan but pre-regular movements anxiety - increased by some aches in the lower abdomen which I'm sure are just stretching but which I can't stop worrying about - and borrowed a friend's home Doppler. I've had no trouble finding the heartbeat, which is a reassurance, but it and these wee flutters I'm starting to feel are all a good bit lower down than I would have expected.
Have posted on the main pregnancy board to ask where the fetus is meant to be at this stage. I would have thought roughly midpoint between pubic bone and naval, but all my 'action' seems to be just above the bikini line. Any more experienced folks know where my fetus should be? And has anyone gotten any good advice from their midwives on rules-of-thumb for when to worry about cramping/aches?
