I'm 31+2 today. I haven't been nauseated at all since 14 weeks or so. I've had a great appetite and everything has been great. Yesterday was no different. I ate and drank plenty, went to work at normal, had dinner about 9pm, and felt perfect. Then two hours later my lower back for a little more sore than it has been, DH tried to rub it and I instantly felt like I was going to be sick and couldn't keep it down. After getting VERY sick I felt fine, but wondered what caused it. Do any of you have any experiences similar?
