Metallic taste

I'm close to 8 weeks pregnant and I'm having a really hard time keeping anything down or eating or drinking in general. Everything taste metallic and smells bad to me, even my favorite foods. I'm constantly dizzy and overwhelmed physically. I'm also having intense muscle pain all over. Is there anything I can try that might help? PS: I have celiac disease so I have very limited options thanks to a strict dairy/ gluten and soy free diet.
