Im pregnant. had an appetite until today. now can't eat a thing - i've got no appetite and extremely nauseous. haven' t eaten yet today. is it normal?

BRAT and meds: It may help to eat bland foods and stick to the brat diet (bananas, rice, apple sauce, toast). Avoid strong flavors that might cause nausea. There are also prescription medications for nausea. You can also try vitamin b6 and doxylamine. Keep meals small with snacks in between to allow adequate time for digestion. Give your OB a call!
