Welcome Snaid I'm in a very similar position to you- 10+3 here, had private scans at 7 and 10 weeks, and also waiting for my harmony test results which I should have back by the end of this week.
I have my 12 week scan on 19th Dec but considering booking a private one for around 16 weeks to break up the wait to 20 weeks. First child for me too, although 3rd pregnancy, which is why I'm so nervous.
How are you feeling generally? I've felt a lot more human, although still so exhausted, over the weekend and it's pretty unnerving!
