How do you make sure you're eating enough or right while pregnant?

Eat what ever you want, but make sure not much sugary or oily foods. Everything in limited. I do the same through out my pregnancy, also I drink similac moms milk through out my pregnancy, it’s not only taste good also it gives me from all the necessary nutrition what I and my baby needs. Coz I do choosy on food so it’s the only thing which is a complete formula for my needy.
