I was dairy free for 5 years when I got pregnant with my first. Cheddar cheese, saltines, frozen grapes and vanilla milkshakes were all that I could keep down.
For most people the queasiness passes by the end of the 1st trimester and your meat eating days will return. Eat what you can, dont stress what you cant. Take a good prenatal if you can but honestly you mostly need folic acid in the 1st trimester...most of the rest of the prenatal is what you need LATER - seriously. Protein is a later requirement. Iron is a later requirement.
The body will take care of your baby.
