Could labor be near or is this just 3rd trimester energy?

The last week I’ve experience more and more Braxton Hicks, back pain and lost some of my mucous plug. I went to the doctor on Thursday with low fluid (5/8) the made me chug a ton of water and hooked me up to a monitor for about 45 minutes until things improved. Things did and they sent me home. I have another appointment on Tuesday but ever since that appointment all I’ve had energy to do is eat, sleep and pee. I feel like I’ve turned into the baby waiting for a baby- lol. Is this normal? I’m 37 weeks 1 day.
