PLEASE HELP!!

Justine
We have been trying for a year and every time I tested this past year I got a bfn. Until last Thursday I got a vvvvfl with evening urine. Thought maybe I messed up the test and so I took one Friday morning fmu. Got a stronger faint line. Took one Sunday fmu got a lighter faint line than Friday. Then today fmu. Got and even fainter line. Almost not there. Period is over a week late....wondering why my lines are not getting darker. Only symptoms I have is that I'm hungry more often and my boobs have pain in them sometimes. But no cramps. No period symptoms. I have tested so much this year and never got any type of a line. All kinds of different tests. Until now. Just worried. I took my first test when my period was exactly a week late...
