Hi,
I have used Lullaby Conceptions LH strips. I think they are great. I only ever get a second line when I am about to ovulate, which helps me as I find getting a true positive a bit tricky. (I am still ovulating I just happen to be one of those women who don't have the knack of turning the stick dark purple!!!) However I did get a true positive this last cycle!
The also have a peeonastick variety of LH strips. So, if you are out or at work you don't need to have a cup you just pee on the stick and put the cap back on and viola!
Lots of luck with your TTC journey.
