I use the OPK Forelife brand and when I am leading up to the LH surge I get a couple of days of what I think is positive. (The lines look fairly even in colour). Then when it is the LH surge the test line is heaps darker than the control line! They never are the same thickness though which does not matter.
I test 2 times a day once I start to get 2 faint lines so I dont miss the surge.
I have 40 day cycles now after having my daughter and dont ovulate until 26-27day.
Good luck with your wedding & loads of baby dust 2 u
