37 weeks and I have morning sickness?

Soo I don't ever puke, I didn't throw up once during the 1st trimester and to be honest I can't even remember the last time I threw up. I woke up in the middle of the night with INSANE heartburn. I took a tums and went back to bed. A couple hours later I wake up and I have the urge to throw up. I tried to lay in bed and have it subside but it didn't so I got up and made myself throw up and felt a little better. Is this normal during the last few weeks? Does this mean he's coming soon? Did anyone else go through this?
