Ok I tested on my opk at lunch and I am on cd 9. Yesterday my ovulation line was there but not as dark as the test line so I clearly had not ovulated. Today there is barely a line there. Can your line go from darker to lighter before you ovulate? I though that it steadily got darker until it was as dark or darker and that means that will ovulate in the next 24-36 hours. Uhggg this is so confusing. There is no way I could have ovulated. But if I did I did'nt miss the boat, wink-wink.
