Originally I started using "Clue" to track my cycle, and switched to "Glow" shortly after. I noticed that they show different fertile windows, so I downloaded "Ovia" to use as a tie breaker. They're all different! Glow says I hit my peak fertility on Jan 31st, Clue says Feb 2nd, and Ovia says Feb 4th. Anyone else get conflicting reports? I've entered in the same information for each so I'm not sure if one is more trustworthy.
