Ovulation Testing

Samantha

I've seen several videos of women TTC. I'm on my 3rd day <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>. According to Glow My fertile window starts today. I should be ovulating 8/26/17 but I don't want to risk missing the chance to inseminate. I wanted to know should I be testing my ovulation twice a day instead of just in the morning? Thanks in advance.
