Well I am despairing of ever getting a positive OPK. Last cycle I wasted money on 3 packs of them, that's 15 days of testing, and I O'd and it didn't pick it up.

This cycle, I have been fertile as far as I can tell for 3 or 4 days, have had 4 OPKs and nothing yet. Today will be my last one, and I suspect I may have O'd last night (less CM today, and I think my cervix has turned).

Anyone else had this experience? I test at 3pm everyday.
