So, i just checked it again. Now the part that is on the Left here, the high end, has changed. The line is barely covered on that side now, where there was a space 7.5 hours ago. Some shadows are creeping and moving there, when I held the light to it. The baby is definately doing something in there, and I absolutely saw it moving about inside. No shadow or pips on the big spacious air end (the right), but who knows by morning??
