I've booked a scan for this evening! Eeeek, excited! Taking my boys with me. Neither will be interested, but oh well!
I've got my 20 week scan date too, for 26th Jan. Also got a 28 week scan (which I requested at 29 weeks as I'll be finished on mat leave!) for 8th April as my last baby was severely growth restricted.
I'm going to book a gender scan for 2nd Jan. I should probably book a midwife appt for the same date.
I've been so good up until now! Now I've gone a bit scan happy! 
I've decided to transfer my care at 20 weeks to one to one midwives. I wasn't sure when I'd do it, but I've decided once I've had my anomoly scan, that's it. I'm doing it!
Today has been a very nauseous day. Not good when at a birth. Not good at all .
