Head is 2nd percentile???

So I’m not much in posting, I usually just really enjoying reading what others have to say - but I’m kind of freaking out. I’m 35w4d and I just had a measurement ultrasound. Apparently, my baby girl’s head is measuring significantly smaller than her body, and much smaller than my 20w ultrasound.

I got a message from my OB saying she’s waiting to hear back from a high risk doctor about what to do next. But she didn’t leave any other information for me. Has anyone else experienced something similar? What ended up happening for you?
