Extreme morning sickness

Brittany • RN mom! 7, 3, and 2. EDD 10/21💙05/17👼

Granted I'm quite a bit overweight but my morning sickness has been so bad I've lost like 10 pounds in the last three days due to a lack of hunger and severe nausea/ vomiting when I do eat. Is there anything I can do to calm this down??? I drink 125oz of water a day and I exercise already I tried ginger ale and threw that up. I'm not even 4 weeks yet so I still got a solid month until I see the doctor so I can't get any help from her yet.
