How long did it take to get diagnosed with hyperemesis gravidarum (HG)?

How long before the doctor did anything or intervened with IVs and or anti nausea medication?

I’m on 2 weeks of severe nausea that persists despite the Vitamin B6/unisom combination. And day 3 or 4 of not keeping anything down that I eat and at least half of what I drink. The doctors office just keeps telling me to stay hydrated as best I can. I feel so weak sometimes it takes all the energy I have to move. But they don’t want me going to the ER for obvious reasons. I’m an essential employee in a home health care office so I have to work.
