missed period - negative test

[Laura P]

I was due on my period on Thursday 02.12.04.  I am now 7 days late.  I have been under no undue stress whatsoever and I normally have a regular 28 day cycle.  I have taken 4 home pregnancy tests in total and 1 test at the doctor's (urine test) yesterday but all tests were negative.

 

I have been experinecing some of the physical symptoms of pregnancy and even have a metallic taste in my mouth.  I have been using no contraception and wonder if I might be pregnant even though all tests have shown negative results.  The test that the nurse did checked for MiU of 25 and above but the other 2 tests I took only checked for MiU of 50 and above.

 

I just want to know if I could be pregnant or if anyone else had had similar experiences of this??????  Your comments would be greatly appreciated.
