Are pregnancy tests ever wrong?

My periods are always regular. I have missed my period the past two months. I have taken three pregnancy tests, but they are show a negative result. Could I still be pregnant? And if I'm not pregnant, then why are my periods not coming?

Urine pregnancy tests may be wrong.  Irregular menses can and should be evaluated with blood tests to determine the cause - a serum pregnancy test should be also run at that time to determine if pregnancy is the reason despite negative urine tests.
