Is labor near??

For the past few days I’ve been noticing some changes. Some days I’m nauseous without much of an appetite, and some days I’m super hungry. I’ll have a day or two of bursts of energy followed by a day of extreme fatigue. A night of insomnia followed by a night of only waking once to use the bathroom and sleeping for 9 hours. Sometimes I’ll have headaches. Sometimes I’ll have a weird taste in my mouth. 38 weeks tomorrow. Can anyone relate?
