For the past few nights I've woken up around 3 am with severe nausea! The worst I've ever had. I do my best to hold down a zofran and go back to bed... After I feel somewhat normal during the day I eat and now tonight I'm having stomach pain, diarehha, and back pain. I've taken a nexium and zofran and I'm exhausted but am not getting any relief. I feel like my stomach may be spoiled? I was having the sulfur burps..I'm miserable and am not sure what's going on. It's been over a span of 3 days now but tonight is the worst.  first time for back pain, diarehha and my stomach is so uncomfortable and feels a little tight. This is my second baby but I was never sick with my first. Should I call the doctor?! Anyone else experience this?!  I'm am 23.3 weeks today.
