ABC-clear blue has 2 digis & the dual hormone is the more expensive one, but it gives you a flashing smiley before your solid smiley and you use FMU. The flashing smiley indicates high fertility & detects the first hormone and the solid smiley indicates that the LH surge has been detected...so the highest chance of fertility. Once you get your solid, you stop testing, but it is great to compare with the IC OPKs. There are instructions for what day you should start using them. The other one just has the solid smiley and detects your 2 most fertile days I believe, but both great. I'd highly recommend giving it a try!
