I'm 10 days early for my mother nature nd have been vomiting for the past 3 days nd during these 3days i been running a fever and my smell is off?

Acute illness.: If your periods are regular & about 30 days apart, it's unlikely that your symptoms are from pregnancy. What you mean by "by smell is off?" If you have a smelly vaginal discharge, that means something different than if your sense of smell is "off." Regardless, vomiting for 3 days with a fever could mean a possibly serious infection. So you need to see a doctor, sooner rather than later.
