I have used the cheapie opks (didn't like em much) and I always got a faint line...but that is still a neg as the LH hormone is always in our bodies. But watch and see if it gets darker. IT needs to be almost as dark as the control or darker than the control for a positive. Also, try to test the same time everyday and don't drink much 2 hours before you test. Fmu isn't too good, as it is too concentrated. Dunno if you knew that info or not, but I just wanted to share

I moved to the CBFM because I didn't like opks at all...I hope they work for ya though! Best of luck and here is some
