indigestion? possible gallstones?

well after a few days of feeling like complete 💩 due to vomiting & indigestion I finally went to the hospital because the pain was unbearable. My BP was 89/52. Three hours later of fluids, zofran, Benadryl, and two doses of reglan and I still feel like absolute crap 😣 my chest and back radiate with pain and I'm still so extremely nauseas. Any ladies have any similar experiences and can offer some tips to soothe the burn and nausea? Or just any words of positivity? This pregnancy has been far from easy.. 😞
