Just got back from fancy scan - paid for half an hour but luckily got sonographer who was absolutely determined to get a decent view and persisted for about an hour to try to convince her to wake up and uncurl from the really tight ball she was in (legs up by her ears with her arms hugging her legs in tightly). Including being sent out for a walk and chocolate and bouncing on a ball. Eventually she stretched and yawn, rubbed her eyes and curled back up again... Just long enough for us to get some pics!!
I asked her about the placenta and she agreed it is low lying, started off saying it didn't look "too" low, but within ten seconds she spotted that the placenta carried on further down and is definitely still touching the os, then later on in the scan she looked again and realised she might have been looking at the wrong thing and pointed to something that apparently looks far more like an os apart from the fact it is right in the middle of the placenta, and she hadn't been looking for it there. So she was unsure, either it's touching or completely covering, she thinks I'll probably have to have a vaginal scan at the 32 week NHS scan for them to be sure. Either way I feel better for knowing a bit more even if it's knowing in an unknowing way!!
