What to eat..!?

Im 9 weeks on my first baby. Im struggling on the food point. I want to be healthy as want my baby to be ok but im going through the all-day sickness so feel nauseous all the time. The only time I don't is when i eat macdonalds fries or kfc fries! I dont want anything else and tonight i cant even bring myself to eat anything as when i look in the cupboards i turn my nose up at it all. I try crackers and small snacks but im really forcing myself to eat at the moment - anyone else like this?
