So tired of negatives

I'm one of those ppl that tell the test how pretty it would look hoping to persuade it to be positive... I pull apart negative tests and hold it to the light hoping to see another line... I just want a positive test already :( my fiance and i want to grow our little family and would cry from joy to see a little bean on a screen... We feel like weve tried everything and at this point its constant heart ache to know that its my body that isnt producing that positive test result.... Hes extremely fertile and so am i so why am i still getting negatives ? :(
