What does morning sickness feel like? For the past 16 hours I've felt like I've got vertigo with a migraine and the stomach flu. Eating actually makes it feel better, but I've still got this dizzy, lightheaded feeling going on. I doubt it's a stomach bug because when I ever have the flu, I can't hold anything down. This is more like nausea on an empty stomach with some vomiting. 9DPO today. Wondering if that's too early??
