Negative pregnancy test but all my symptoms are those of early pregnancy. i exercise and eat healthy how is this possible?

Other possibilities: While i don't know what "all the symptoms" are from your point of view, the symptoms we normally associate with early pregnancy are merely suggestive and not definitive. They are all nonspecific and could have other explanations. While you ought to repeat the pregnancy test in a few days to be certain, you should consider getting a check up.
