I don't want to break all hope but to be honest it doesn't really mean much you maybe gearing up to ovulate you may just have a high hormone level , I had 6days of positive opks last month and nothing at all so I'm guessing my body just struggled to o but I hope yours is more positive sorry I can't give much help or advice as im not sure either but I hope this helps it could literally mean you just have an lh surge , sorry I couldn't help more x
