Breech and low fluids

Im officially 37 weeks 1 days today. Yesterday I had to an ultrasound to see if baby was in the right position and to check fluids. Baby is of course breech and the lowest they want fluids to be is a 5 and I’m a 5.2 :( Doctor had me go get monitored and baby was still moving fine but they wanted me to drink a lot a lot of water and rest and have another ultrasound today to see if fluids replenished. Anyone have experience with this? I’m feeling so upset and worried
