My 20 week scan is next Tuesday (5th).
I've got it into my head that there won't be a heartbeat or something will really be wrong.
Before my 12 week scan I had convinced myself that I'd had a mmc. It was fine and baby was measuring perfectly, brain was forming nicely, as was the heart (beating away) and there was fluid in the stomach which the sonography said was a good sign of things working properly.
Since then I think I have a bit of a bump, but it changes all the time and because I'm plus size, I'm also flabby on my tummy.
I think I may have felt some flutterings that feel like spasms but they're very sporadic.
I'm really anxious
