diarrehea, acid reflux, & can't sleep on my sides or back

Stephanie R.
I'm 30 weeks and 6 days pregnant. Yesterday I started having bad liquid diarrhea & acid reflux, my stomach looked huge until after using the bathroom about 10 times. Now I can't move without my body hurting & I can't lay on my sides or back. & it seems like my baby is moving nonstop. What does this mean??
