Problem

Was very dizzy for 2days, neaseated, I felt like i was going to pass out. Today I was ok just neaseated. Light cramps today that moves from one side to another. And my back hurts badly standing is very ruff and walking, migraines. Two days ago shortness of breath for to days and one of those days a very bad anxiety attack. Af due in seven days. Is this something else besides pregnancy, and i need to see a doctor?
