Really don't envy you labouring in this heat small, I'm only 19 weeks and I can't bear it! Exciting times though! Hope things kick off properly for you soon and it goes smoothly. 
Booked in for a private scan on Monday, partly because I was concerned movements weren't really getting any stronger since the first flutters I felt at 13 weeks, but mainly so DS (age 3) could come and see baby. He's been watching the belly button episode of Nina and the Neurons, which shows an ultrasound, and is utterly fascinated by all things baby. He was absolutely thrilled and kept asking to hear the heartbeat again and again. The sonographer was great and really indulged him, such a lovely experience, well worth the money.
Also discovered that the placenta which was at the top last time we looked is now fully anterior, which explains the movements not feeling any stronger. Was reassuring to see baby wriggling all over the place whilst hardly feeling anything, so I can calm down a little on that front now!
We decided to find out the sex. DH and I would have preferred a surprise, but DS has been utterly convinced it's a girl ever since we told him and got cross if you suggested it could be a boy, so we thought it would be safest to find out. Just as well we did as it is indeed a boy. DS was in denial for a while, but he's come around to the idea now and keeps lifting up my top asking if he can talk to his little brother. I'm delighted, I know you're not supposed to have a preference, and I would have been happy either way after the troubles we've had, but I really love the idea of him having a brother and am getting quite tearful imagining the two of them running around together, thick as thieves, in years to come.
Sorry for the long me me me post, but all of a sudden it feels really real. All of a sudden I'm actually excited. It's wonderful!
