Did I ovulate at all? I don't think I will ever know what happened..

CR
Okay so originally I ovulated between May 28 - June 4. But now that my period is 6 days late Glow is moving my ovulation date. I didn't get EWCM at all. Now I don't know when I ovulated or when I was supposed to ovulate... I'm late and keep getting BFNs. Any advice or comments are welcome...
