Any words of encouragment?

i am really depressed today, i thought i had my BFP last night but it turned out it was just an evap line. we have only been trying since August, but its still frustrating. I am on cycle day 23 today ... my period is due today but no sign of AF......i havent had any real preggo symptoms, just been more tired than usual and last night i got kinda naseous. Sometimes my cycle can be irregular so its hard to pinpoint when im ovulating. anyways, anybody have any words of encouragment for me, im getting really discouraged.....
