So the past 2 months I've used the digital CBE OPK's and loved them. But wanted to try to save a little $$$ and bought the grocery store brand OPK's that were on sale. I used one for the first time this morning, and found how difficult they are to read!! The instructions said that if the line was as dark as the control it was positive, no line or lighter line was negative. I got an instant line in the test slot, that was just a faint bit lighter than the control. But it looked positive to me. I know you're supposed to test in the afternoon, so I'm going to try again later today as well.
So my question, does a test line always show up with these and you have to determine the SHADE of the line? If so, I'm going back to digital. Way to hard to read!
