TTC and losing hope...

Well seen another Facebook post about being pregnant and having that pretty dark positive.... Me and my husband have been trying for a 1 year 1/2 and nothing.... I'm 8 days from my highest peak day and I been having heart burn(which I have NEVER had) and my best friend said that was her first symptom so I just hope and pray it is my month this month.... I'm giving up and just want to cry....
