I have the same thing. I had hyperemisis graviderum. I was vomiting non stop for over 3 days. Had to go to the ER for IV fluids. So if u cant keep anything down and not even water. And you start losing weight. I lost 10 lbs. You should go ask your dr. At the ER they perscribed me meds that have really helped. I know taking meds isnt the best. But if you are so sick it can be dangerous for you and your baby. Of course always check with your dr.
I'm a nurse and I agree. Get checked out. They may need to hydrate you better or be able to treat the nausea with meds.
