Two Clearblue tests done the same day. One advanced digital another advanced digital for monitor. Which one to believe? It happened to be already some months back with the same brand. That time according to monitor i was ovulating and according to the stick reader i was Low. Never questioned it, got busy with life. This time is my first cycle (44 years old in July) when according to monitor I did not ovulate. Always on days 12-14 today is day 16 and I think I am out this month.

Any ideas re why these tests show such different results???
