They tell you to eat small meals not huge meals right now. And in super early pregnancy they tell you the baby gets its nutrition from you, not the food you eat. Once baby is older that's when the food intake matters.

This is how I was with my second. I barely ate at all for the first 12 weeks. Just keep up with your prenatals. You can try sea bands for nausea. They really helped me. Also, preggie pops.

You can try gravol

My cousin wife is going through the same thing. Also my other cousin was the same. She had to talk to the doctor and he gave her this lil pill and it helped her to be able to eat

At this early you dont need to worry about how much youre eating, as long as youre getting some nutrition. Make sure youre taking prenatals to get your vitamins and minerals, and talk to your doctor about what you can do about the nausea.
