@Mrsbluebell17 I've been waking up anytime between 3-6am most days too! Utterly knackered for the rest of the day after that! Could you not call the hospital maternity ward and ask if you could possibly go through scan dates with them? I did that and they were absolutely fine - we chose a time and date together that suited. Takes the mystery and worry out of it then.
@Oysterbabe Lucky you! My first TV scan (to rule out ectopic) was absolutely spot on at 7+3 but when I had my 2nd TV scan (clot scare) at 8+5 it was 3 days under the mean size so of course that worries me. I know at that stage the measurements aren't absolutely accurate and that the smallest deviation can cause days off, but it doesn't stop me worrying. (Naively, I'm sure) I'd rather bigger than smaller, if you know what I mean!
My cravings have been absolutely all over the place! Tuna cheese melt was all I could think of for a whole week at 6-7 weeks, then McDonald's apple pie (had to be McD) for another few days. All clearly very healthy choices! 
Aversions on the other hand have NOT been fun - can't stand being in the same room as red wine, whiskey or Tabasco (3 of my favourite things) and a certain carex handwash or garlic being cooked is enough to send me running!
