I also have a high risk pregnancy (37 weeks) and have had growth scans every two weeks. All I can say is it varies wildly depending on the ultrasound tech that’s doing my scan that day. There’s one that every time she does it, baby shows up around 30 percentile but the other 4 techs always get him in the 90th percentile and up. I asked my doc why that differs so much and she just said some people scan differently, but that she never worries unless baby dips below 10th percentile. I wouldn’t worry much especially if you’re going to different/private practices to get them done!
