Query: Did not work for me...Showed no more than two bars all month yet I'm pregnant.

I ordered this under the advice of my doctor. She told me it didn't look like I was ovulating regularly and that this test would help determine if/when I did. So I ordered it and peed on sticks everdy for 20+ days, and I NEVER got more than two bars (moderate fertility) the entire month! I never got a peak with a little egg so I just assumed I wasn't ovulating like the tests at the doctor's office said. Well....I just took a pregnancy test on day 36 and got a BFP (big fat positive). I'm upset that I spent a freaking fortune on a machine that never detected my fertility even though I obviously at some point was very fertile. I'm thrilled to be pregnant, but not at all happy that this machine didn't work the way it was supposed to as expensive as it is - and yes, I did pee at the same time every single day.
