Any one else have severe nausea and vomiting? If so, how are you managing?

I had to go to the ER today to get fluids, I haven’t ate or drank in a week and down 6lbs in a week as well. Throwing up ALL day, and it’s all stomach bile and it’s literally draining all the energy out of me 😭 Dr gave me Zofran, reglan and phenergan but I don’t wanna risk my baby having defects 😩 any input would be great!! Due March 18!
