I have been charting my CM using the Billings Ovulation Method and now am also using the ovunow tests. A few days before I suspected I would ovulate the tests just came up with the control line. Then the next day i got a feint line in the test line and the following day and darker line still, but if I'm honest with myself not as dark as the control line (close though). The day after that a feint line again. The previous cycle I used Fortel and got a really strong positive.

My question is can I assume the line on the darkest day was a positive? It seems to coincide with my CM charting. We BD'd anyway but if we do conceive or even if we don't I want to be sure of what might have happened.

Thx
