If I were taking them, that would be a 'nearly' positive, but everyone is different and it could be a positive for you, so TBH you'll probably have to take the OPK's for an entire cycle to know what a positive is for you. lot's of those strips only get dark on half of the test line IYKWIM so, like I said, that could very well be a positive, so get to BD'ing just in case! Good Luck!
