Glow Ovulation Date

Samantha

Has anyone ver had their Glow Ovulation date be wrong? I'm tracking my date with Glow and <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Period Tracker</a> and they're both different. This is my first time TTC and I don't want to miss my peak and the chance for insemination. Any guidance is greatly appreciated.
