Has anyone developed morning sickness half way through their pregnancy? I have not been sick at all to this point. I was very fatigued until week 12, but otherwise no vomiting and very little nausea. I'm now at 23 weeks and haven't kept food down in 3 days. I can't tell if this is a bug or my new normal, but it's terrible. I called and spoke with my doctors nurse who just told me to eat crackers.... Does anyone have any experience with late onset morning sickness or a stomach bug while pregnant?
