Only on CD 6 and OPK has second line already

Ja

So my period has shortened and lightened in the two cycles I've had since mc in June...I took an opk today just to see what it looked like and the second line is there already. Last cycle I didn't even see a second line until around CD 12.

I normally O around CD 14-16. Do you think I will O sooner this cycle since it is already showing up, or will I keep getting "almost positives"?
