Hugs glad you got some results I can't remember what percentile DD was but at one stage her head wasn't growing so I had to have steroids. Your ob sounds like he is doing things right and with the monitoring and scans.
At close to term hopefully if baby is delivered all will be ok and hopefully no special care DD was lucky she came out ok.
Hugs chicky I know exactly how you feel just keep you mount instincts I you feel something is wrong go to hospital.
Best of luck.
