What is going on?!?

Lisa

I have been tracking for 7 months now. I always have a 12/13 day leutal phase. Today is day 14 and still BFN. I have had a tiny bit of brown discharge off and on since Saturday and slight cramps come and go. I always have pretty bad cramps on day one of my period and nothing yet. Do you think I’m out this month? I rarely spot before my period.
