I m 16 weeks 2 days and symptoms are from bad to worst. I wake up hungry I eat and the everything just comes right out. I'll have lunch or dinner and same thing happens. I cant seem to keep food down. I also have headaches all day long. Only thing that helps is sleeping which I can't get enough of I take two 2-3 hour naps just about every day. I love it that I'm pregnant I just want to be able to enjoy it.
