Nice one Primary, congratulations! 
Great to read about all the healthy heartbeats too 
Belated birthday greetings Isla
We're probably going to find out the sex of this baby. Dd has so many clothes so it would be good to know whether they will be needed again or not. (we're definitely stopping at two).
With dd, we did try to find out at the 20w scan but she was giving nothing away! In the end we were quite glad about that as we could look forward to the surprise. But I can also see the point that it might help you to bond with the baby.
I'll soon be ten weeks and still no scan date. Apparently it can take up to two weeks AFTER the booking in appointment to come through. Only had my booking in appointment on Monday
