High Amniotic Fluid Levels

Has anyone else had this? My doctor was worried mine were low because I’ve been losing weight, it’s hot out and I’m dehydrated, etc, but when they checked last week they were actually really high. They checked again today and they’re slightly higher, 26 AFI.

Apparently normal is 15-20, 25 is considered really high. My doctor is checking again next week and all she said was we can’t get to 30.

Has anyone else had this? I’m 37 weeks 2 days, if it keeps getting higher what will they need to do?
