Congratulations on the great scan amiseeingright! I'm glad you are starting to enjoy things now. I alternate between being terrified of two under 2 (almost) and being so excited that I'm creating another person as amazing as my son 
magicducky, if it's not too late, definately try to get some anaesthetic cream, then you won't feel a thing. Otherwise,
and breathe 
The GTT is usual at 28 weeks, I've only heard of it being done early if the is a previous history of GD....maybe it's just your trust? Might be worth checking if you get another test later on as often it won't present until later in the pregnancy.
Glad your mum is stable and in a safe place neha, she's lucky to have you looking out for her!
12 weeks today! Only 1 week until scan
