3 weeks nausea

Is anybody or has anybody experience nausea for 3 weeks straight 😷

I'm 10 weeks today and I still cant eat much and I could sleep 24/7 and if I walk around my head bangs and feeling faint but I'm not surprised with little food I'm having.

I'm wondering if its my prenatal vitamins folic acid tablets, I've changed them twice.

Any suggestions please 🤷🏼‍♀️
