Severe morning sickness

Hello ladies!

I'm 9 weeks pregnant and starting last week my morning sickness has gotten so bad. I feel like I have the stomach flu 24/7. I've been doing alright keeping fluids down but food is a no go. I've called my OB but it was on a Friday and I haven't heard back. Not sure what to do. I've already lost 7lbs. I have Zofran from a previous surgery and I'm tempted to take it, just to find some relief. Anyone else take Zofran in first trimester? I know some OB consider it an big NO but then some woman are prescribed it. Losing my mind. 🥲 thanks ladies ❤
