Lack of appetite in first trimester

Hi mommies! I sometimes have lack of appetite. Like today, i only had peanut butter toast and Mamee monster snack (without the powder) w a glass of hot milo for lunch. I was feeling a little nauseous & only want bland food. But I’m quite concerned abt my nutrition. What do u usually eat when u feel this way? Thanks in advance for sharing 😍#pleasehelp #firsttrimester
