Anonymous wrote:OP here. Thanks for the advice. Is that true for all OPKs? I use Wondfo. The instructions say that a "positive" is when the test line is equal to, or darker than, the control line. I would definitely say the test line was equal to on my "first positive day", then darker on the "second positive day," and darkest today on my "third positive day." I just thought because it technically was equal to or darker than, that they were all positives. I wish the instructions were a little more clear on that! That means that I should probably try to DTD today since it was darkest of all.
Is it possible that I would get an even darker test line tomorrow, so 4 days in a row of this progression??
That PP who said it's not possible to have this is wrong. I routinely get 2 days of positives. Normally O happens within 48 hours of your first positive. What IS possible is that you might have some hormonal imbalance causing longer surges with or without ovulation. Keep tracking temps and pay attention to your CM.
