Also...with OPK's I've heard a lighter than the control line is a negative, but then I've also read that especially with the IC ones they may not ever get as dark as the control?! So do I just count my first + as the first one that I get any line on, even a faint one?! And yes! I did read and hear that using an instead cup and having an orgasm bf and after are all helpful, as well as lying propped up for awhile. All advice and suggestions are helpful! Thanks everyone so much!
