So, Im a classic 28 day cycle.

Today is CD10 and I just got a +OPK. My naturopath keeps saying O'ing on day 12 is a little too early, but i cannot see an issue with O'ing on day 12 as o'ing on cd12 is regular.

I am a little concerned with o'ing on day 11 tho. i guess it is a possibility i still could O on day 12, considering i tested + tonight.

WDYT? is CD10 too early to O?
