Am I harming my baby?

So it’s been so rough since I got pregnant I am now 25 weeks and for the last week I haven’t been able to have a proper meal I eat at least two times a day like a bagel with cream cheese or scrambled eggs or cookies with milk I do drink my vitamins every day I’ve been up all morning and it’s already 12 and I haven’t eaten nothing I’m scared it could harm my baby if I don’t eat properly.
