To ovulate a week and a half before you normally do? I usually test around CD15 and get my positive ovulation test at CD20 . but I randomly took a clear blue digital advanced ovulation test on CD9 and got peak fertility, meaning I'll ovulate within the two days. Yesterday morning I took another clear blue test and it read low (negative)

Is it normal to ovulate earlier?

I still had creamy/tacky CM, instead of egg white like I normally do when I'm about to ovulate...
