Fluid concern

I am 36 almost 37 weeks pregnant with our first. On Monday i had an ultrasound and the doctor said she’s not worried but the fluid around the baby is at a 8.5 where as 10 is normal. She said if it gets to 5 we have to talk induction. She scheduled me for another ultrasound for this coming Monday

Is there anything i can do to increase the fluid? Should i be worried? Already I’m worried about the delivery with this pandemic so trying not to add anything else to the list
