Help!!!

Megan
So far in my pregnancy I've lost 20 pounds due to throwing up (hyperemesis) I've tried ginger, small meals, the brat diet, peppermint tea, peppermint oil, only drinking fluids, and my doctor has prescribed me 4 different medications one being a suppository not fun... I go to the ER every other day for fluids because I'm so dehydrated all the time. Im 10 and a half weeks and im worried my bun isnt getting the fluid it needs. What should I do.
