Hey been ttc #2 since may. Decided to use opk this cycle. On my fertile week according to app so started testing Monday and due to O on Sunday or there about a. Using cheap strip tests off eBay. First two had faint lines in test window which I was aware meant the surge is coming and wait till both lines are of equal strength? Tested today day 3 and its totally (-) no faint line at all?? Help please
Thank you
