Nausea in early pregnancy

Magen
Hello! I'm 5w 5d here, and my number one problem is eating right! Pre pregnancy I followed a plant based diet most all of the time with bits of dairy here and there, but this pregnancy has made me want to gag at every vegetable but baked potatoes. I was hoping to have the healthiest diet during this crucial time... But I just can't stomach anything I used to eat because I'm so nauseous!! I literally ate bearitos cheese puffs for dinner last night. Please help lol! Anyone else having this problem?
