White creamy CM

Does your CM have to be egg white CM because during my fertile window I've had creamy white cm not any egg white CM so is that a chance of being fertile or non fertile and according Glow I was supposed to ovulate on the 31st of this month and I still have the white creamy cm, I guess I just didn't ovulate this month cuz it has been the white creamy cm does anyone have any answers and I know I don't have any kind of infections
