Re: I need your eyes...what do you think of this OPK?
With most OPKs, for it to be considered positive, the test line needs to be at least as dark, if not darker, than the control line. What do the directions say?
Taking them daily, your line should get darker- positive when the test line is (in my experience) darker than the control line. Most women ovulate 24-36 hours after getting a positive OPK. But definitely read your directions
