I am confused...I took a first response OPK test and it looked like the two lines were the same color. Because it seems early for me to O, I wanted to double check so I bought a digital one with the smiley faces. It did not give me a smiley face. Do you think that I should believe the digital one because it gives you a clear cut answer? I never used OPK's before so I am not sure how this all works. Thanks for the help.
