Mlm, we are all worrying, Its natural, especially given our experiences before.
When I was 9+4 weeks I was convinced it was dead as had no symptoms for a week. I cried down the phone to my mum telling that I just knew something was wrong so I paid for a private scan and there was my bean, very happy and alive. Symptoms will come and go.
Your bubs has likely moved position and don't forget, although you heard the HB using the Doppler already, it is still so early to be hearing it reliably every time.
Bobster, I still need to go and touch and feel the pushchairs before we make a firm decision on it. Although we don't want to spend heaps of money, we've learnt the hard way on other things we've bought (non baby stuff) that your better off paying a little more if it saves you buying twice and I know my parents have the same view. But we totally won't be paying like £800 upwards because we do have a budget and I believe we can get what we would like for under £800.
DH also wants an isofix car seat which im not sure if you could then use the pushchair chassis to stick the car seat on but being winter we'd likely stick to the bassinet for that so it keeps snug and warm. Hmm needs more research.
Mrs phez, did you tell people yet? Rubbish about your scans- you will need to work on DH some more!
