So I use the Clearblue adavanced digital ovulation test. I got busy with something else and forgot to come up and check it in eight minutes. Per the directions I ejected the tip to see my results again for another two minutes. This result put me at high fertility, it was a flashing smiley face.  Worried that I did something wrong, and before I went back and read the directions again more thoroughly, I peed and tested again. My new result is a blank circle - low fertility. The first test was taken after holding my urine for 6+ hours. The second one was not that long after the first one. Could this fact be why the second test came up low? I'm trying to figure out what resulted put into my Glow data. Sorry for my silly question that came up as a result of negligence. Any help that can be provided would be appreciated.
