Requesting "anxiety" ultrasound at 34 weeks (CW - mentions loss)

I'm 33wks pregnant today with our rainbow baby and I'm 38 yro. I had a loss at 11wks back in December 23. Given my age, we quickly moved to trying again and I was pregnant in late February 24. My OB practice keeps a pretty standard schedule of monthly, and now after 30 weeks, bi-weekly appointments. But the only thing that happens at these appointments is a tape measurement of my uterus, blood pressure, weight and a quick scan with a doppler. I would really like ultrasound confirmation nothing is wrong. I have an anterior placenta so I've felt this baby's movement less than my son's. I feel like I've done an ok job keeping my anxiety during this pregnancy in check after our loss, but it is HARD. I'd really like more information and I'm not sure what to say. We are so close - I just want our daughter here and healthy.
