For ladies who normally have 28 cycle day and longer......Have you O on CD 10 or sooner? Reason why I'm asking is......I'm gonna start testing with OPK on CD 10 and I don't wanna start too late....This will be my second cycle testing with OPK....Last cycle I started testing a few days after AF and O on CD 14.....What does everyone think?
