Help!

We have been TTC for almost a year now, and I have just started opk testing and temp testing for a month or so as well. I have been relying primarily on my CM checks, which have been consistent without testing otherwise. According to my CM check, I still have a moderate amount of ewcm, but according to the apps I am using, and my temp, I am 2dpo. Even though my ewcm was where it should be for around O time, all my opk tests were neg THE whole time. What does this mean?...
