Low fluid

Katie • Wife,Mother of 3
So had to go to labor and delivery yesterday to monitor baby's movements as it changed quickly very unlike him. After 30 minutes everything started looking better on his movements but Dr ordered an ultrasound to monitor his breathing and movements. All looked great there too until dr came in and said that the fluid abound him is low but not to where we needed to do anything right then but will check it next Wednesday and if no change or gets worse will talk about being induced. I'll be 38 weeks on thursday. I drink water constantly and I don't Push My limits. just wondering if this has happened to anyone else?
