Tmi alert! Need advice!

Im 33 weeks pregnant and I havent been able to keep anything down today at all I'm having stomach pains that go from my pelvic area to under my ribs and watery poo too. I'm in alot of pain and feel like shit. Idk why this would come out of no were or if I should be worried about the baby. She is moving around alot today though so that's a plus but I just don't feel right. What could be going on that's causing my body to empty its self out to the point it hurts.
