Nausea and vomiting

Ca

I’m almost 10 weeks pregnant with my third. I have truly never been so sick in my life. Yesterday I was so nauseous I couldn’t hardly move and had maybe 8oz of fluids and not able to eat hardly anything. Today I’ve vomited until my throat bled and have been so nauseous since, this seems to be getting worse by the day and not better. Does anyone have any recommendations on rx medication that I can request from my ob to help this?? Im very leery of zofran, I had a friend with a child with a very severe heart defect and hers was linked to zofran. I’m working full time and have 2 little ones at home that need me.

I have tried:

Preggie pops

Ginger ale

Crackers

Small frequent meals

Gatorade

Acupressure bands

Peppermint

Carb rich foods
