I am about 7 weeks pregnant, and I have not had any previous form of morning sickness. Today, I have been running a low grade fever with sinus-like symptoms (runny nose, frequent sneezing, and sore throat). Tonight, I have not been able to sleep much from the severity of the previously mentioned symptoms. Suddenly, after dozing off a moment, I woke up to projectile vomiting, which continued several subsequent times. I have RARELY ever vomited in my life at all... Should I be concerned that this is more serious than morning sickness ?
