loss of appetite

 My husband is a trucker, he called me to say goodnight and that he will be home tomorrow morning. He asked how much I ate today. I told him I've hardly eaten all day. He told me to go eat something and go to bed. So I made a bagel, took two bites and tossed it in the garbage. I've been in pain on and off the past few days, and been soo thirsty and only wanting to drink cold water. Could all of this be signs of labor? I'm 34+4 I will be 35 weeks this Saturday.
