Do you think it's better to starve until the next day or eat junk food when hungry?

Currently 24 weeks but very nauseous, esp at night so occasionally i couldnt eat my dinner or eat very little. Thing is, I'll be very hungry later, but don't have "healthy food" (which I can stomach) at home only have junk food like chocolates, biscuits and instant noodles or frozen finger food (which I can still barely eat). Was wondering if it would be better to snack on junk food so at least I have something in my stomach, or just avoid the junk food and dont eat until I feel better and eat healthier the next day? What do you guys think? #firsttimemom #advicepls #FTM #firstbaby
