I hate how when I use ovulation tests to get accurate results, and input them into this app, glow changes the fertile window incorrectly! On clearblue advanced digital, yesterday showed low fertility and today showed blinking high. Usually I have four days of blinking before peak. But glow changes my calendar to make it look like I'm already 3 days into my fertile window... It's just totally inaccurate. It actually matters very little because the opk are what I'm basing everything on, but I'm very type a and it drives me nuts! Any of you experiencing this?
