If My AF Was Late Would I "O" Late?

*Allie
Thoughts? 
My period was 8 days late last month, does that mayb mean I would "O" late this month? Plz Help! Im on CD 19 and so far my OPK's havent shown that Ive ovulated! Ive got faint lines but not one thats as dark or darker than the control line. I take one n the morning and one in the evening, and have been since CD 8!
