All symptoms of pregnancy but negative test? anyone had this happen to them? If so what was your end result?

It's been a few weeks. I have every symtom of pregancy but I took 3 negitive pregancy tests. The tests were done spread out. Maybe I tested to early or somthing? I'm just scared there is something really wrong with me if I'm not pregnant.
Going to a doctor Monday. Anyone had this happen to them or your spouse? If so what happend? And what was the end result?

We are trying to have a baby. So we're really hoping that it is a pregancy. We were excited at 1st but highly disappointed when the tests came out negative. But I'm still having symtoms and no period.
