Eating with nausea

Manzini

Hello, this is my second pregnancy although I never went through with the first one. I'm currently at a higher risk for miscarriage but I get so nauseous and can't eat. I've had an eating disorder before so it comes sort of easily if I'm nauseous enough to not eat. Any tips on how to reduce nausea, specific foods that don't gross you out so much or tips on how to eat with nausea ?
