I'm 19 weeks tomorrow, we had our anatomy scan today. Baby girl was being super difficult and wouldn't flip over so they couldn't see everything they needed to see, so we have to come back in 4 weeks to try again.

During the US, the radiology doctor came in and said baby was measuring 1 week behind and she worries about chromosome issues, (even though we've had all genetic testing which showed no issues) and recommends an amniocentesis.

My OB says since I already have pre existing blood pressure issues, he would expect a smaller baby and not to worry. He doesn't feel an amniocentesis is necessary.

Anyone had a similar story and baby ended up being ok? I'm just freaking out and need some reassurance.

Here is our 3D image from the scan today.
