Growth ultrasound?


Anyone have a growth ultrasound? I’m 34 and being monitored by maternal fetal medicine because I have a history of dvt from a surgery and I have pretty bad asthma. The doctor prescribed a maintenance inhaler and warned me that it’s possible the baby may have restricted growth. They scheduled me for this next ultrasound at 29 weeks. They said she was perfect at the anatomy scan at 19w3d but I know a lot can happen in that time. Just wondering if anyone has had this and what to expect and more specifically if anyone has had any issues with their maintenance inhaler causing fetal growth problems.
