Polyhydramnios

I’m 37.5 weeks and have a scheduled csection at 39 weeks. My dr doesn’t seem worried at all that my fluid is measuring 35cm! Has anyone ever had this high of fluid? I’ve been getting ultrasounds every week and they say baby looks 100% healthy and strong.. however, I’m getting worried that my dr doesn’t seem concerned because of how many stories I have read.

I have two other kids and had Polyhydramnios with them as well but went into labor early with them. But they were both healthy and are still healthy today
