Actually OPK's detect your LH surge which happens when your body is gearing up to ovulate. So you can get a negative OPK before you actually ovulate. A woman normally ovulates 12 - 36 hours after you get your first positive. Your test line must be as dark as or darker than the control line for it to be a positive. Good luck!!!!!
