At what point do I call my doc? Tmi no pics

I woke up this am at 3am to severe acid reflux, so decided to drink a cup of milk.  Well, the milk was bad, or at least it tasted that way, I only drank a sip then dumped it along with the rest in the gallon.  Minutes later I was in the bathroom puking everything I ate since lunch the day before. Everytime I've aten today, I think I'm fine till a few hours later.  I've thrown up breakfast, lunch and dinner now.  I only had pbj on an English muffin, water, pb ritz crackers, Gatorade, and some soup.  I've also had pretty bad diharriah (I can't spell and it won't autocorrect) but that part is getting better.  I'm no longer peeing out of my butt.  Sorry, for the tmi.  It's now 9:35pm here.   I'm 33 weeks tomorrow.  I do go in tomorrow to my obgyn for nst, u/s and ob apt.  I don't have a fever anymore.  The first time I took it at 9am it was 100.1, then 99.9 at 3pm and just now its gone 98.7.
