So I have been taking Clear Blue Advance and First Response ovulation tests. I use the Clear Blue in the morning and FR in the evening. Yesterday my Clear Blue had no smiley face and my FR has a line (it was light so the test wasn't positive.) This morning my Clear Blue test had a blinking smiley face but my FR test was lighter than it was yesterday (you could barely see a line at all.) Obviously the Clear Blue is picking up these changes, shouldn't the FR line be getting darker not lighter at this point? Today is cycle day 11 for me. I'm just really confused.
