am I going crazy?

Vivian
I have taken some time away from the app to see if maybe I'm just causing stress resulting in not getting pregnant. Anyway, it's been 2 months and nothing.
I usually spot before my period, like, from the end of predicted ovulation week until my next period. But, this month, NOTHING. All I have had is CM, to the point where I think I'm getting my period early & it's just CM. I can feel it, sorry for the TMI. 
My period is due Tuesday & I took a test.. negative. Anyone experience this the month they got pregnant? Or am I out? 
Thanks!!!!
