First Pregnancy Advice??

It’s my first ever pregnancy and I’m only 5 weeks along and I’m filled with questions. my first doctors appointment isn’t for another month and I want to make sure I’m doing everything right for my baby in the meantime. I have clinical anxiety which I’m hoping I’ll be able to manage okay, and I also have celiac disease. What are the best gluten free foods for morning sickness? Any other tips or advice for a first time mama?
