I thought I was done with nausea! Apparently not. I was up all Sunday night vomiting, and when I called my doctor first thing in the morning they told me to go to the emergency room. They gave me some Zofran and some IV fluids, and checked to make sure all was well with the fetus, then sent me home. Scary and unpleasant, but not dangerous. Hopefully there will not be a repeat of this.
