Low measurements at 30 weeks

[MuggleMummy]

I am 30+5 and had a growth scan today. Originally having growth scans due to a low PAPP-A level. I was also high risk for Down's syndrome, but I had the safe test at 12 weeks and it came back negative. The consultant has currently got me on 2 weekly scans to check the growth of the baby as it is measuring small (only just in the normal range). Today she has said my next scan will be with a different consultant as she wants a second opinion. I kept asking her what she was looking for and she just wouldn't answer the question. She also took some of my measurements, height, shoe size etc.

I don't really know what I'm looking for from this thread but I just feel really emotional and like I don't know what is going on. Does anyone have any idea what she could be worried about? I assume she is trying to stop me being stressed about it, but it really isn't working!

I've had quite a few scans with the same consultant as DC1 was born at 33+4 so she is also monitoring signs for this one to come early. Currently she said there are none.

TIA
