passme could be wind, indigestion or maybe you've tweaked a muscle slightly, especially if you have bloating/bump & are lifting. I had twinge the other day alternately between left & right all down my front, think because of the lifting & twisting with DD & the stretching going on in there. If it doesn't improve, or gets worse, you might want to call NHS direct/MW/GP, although its too high up to be appendix or anything.
Sorry to hear the news Westwinger that's hard. Never good to hear anyone is poorly, whether they're old/resigned to it/very likely to recover. You just don't want anyone to go through it.
I think our hospital says they may be able to tell you at the 20wk scan but its not a priority. Unless Grub isn't shy though & lets it all hang out, we don't want to know.
Keep feeling thuds & what can't be wind-related pops but I can't quite believe its movement as it seems so early, but enjoy feeling it anyway :)
Thought I was emerging from the ms wilderness but it came back full force yesterday, feeling queasy on and off all day again, whereas it had been slightly in the morning & evening. Didn't vom so its all good!! 
Finally, this time tomorrow I will hopefully be walking into the hospital with a nearly full bladder, trying to ignore that fact & not think about weeing, waiting impatiently for the scan!!
