Wonderfully, my scan also lasted about 20 minutes and the sonographer talked us through absolutely everything she was looking at; pointing things out, explaining what she was looking for and that things were "as she'd expect". We had to pop back in after emptying my bladder though because he was moving so much she couldn't get a picture of the spine and thankfully with me lying on my side, she managed to photograph it. It's such a lovely experience, I particularly enjoyed seeing his little hands and feet - so cute! Enjoy it and best of luck! Teeee, good luck to you also!
I actually ended up calling the midwife today because bub still wasn't really moving this morning. I left a voicemail but she hasn't got back to me yet! There is an advice line I could've rung though if I was really worried but thankfully after I'd called, he of course started jiggling around! So all seems okay again now. He's moved really low again though whereas over the weekend he was around my belly button. I guess maybe he's flipped around!
Sorry to those suffering with numbness during sleep/lying - I've not got any advice I'm afraid! The only weird thing I experience is cramp in my legs when I stretch but thankfully it's fleeting!
