Been nauseous and or vomiting for over 2 mths. Miss a period but had two since. Nauseous everytime I try to eat. Low apatite, low apatite and fatigue?

Nausea and emesis. You have symptoms that can be associated with Gall Bladder disease or acid peptic disease. I would recommend that you see a gastroenterologist for an abdominal ultrasound and amylase and lipase and liver function testing.
