WHAT DO I DO?!

EricaLynn • 21. Libra. Expecting Bodhi Scott 1.1.17.
I woke up in the middle of the night with horrible indigestion, as I do a lot of nights. 
I'm almost 34 weeks pregnant so I figured it was normal. 
I had pains that were almost period like, but were most likely just poop cramps, so I got up to use the bathroom. I had very soft BM, not quite watery though. 
That's when I started throwing up. It was almost projectile & I saw stars. I've never experienced that before! 
I just don't know if this is an early sign of labor, if I'm paranoid or if this is some REALLY bad food poisoning that I've never felt before.
I'm calling the doctor when my grandmother wakes up, but it's currently 6am & would like some sort of answers ASAP. :(
