CM before AF/after implantation?

Elizabeth

I’m new to TTC so I don’t know my CM as well as I should. This is what it looks like today 4 days before AF. I don’t remember ever having discharge at this stage.. I’ve had cramping but no spotting for a few days off and on now. Fatigue (waking up exhausted) increased CM and today my breasts are sore. Hoping but who knows! Waiting until Tuesday to test.
