Question about Easy@home ovulation kit

Janice • Pregnant after first round of Ivf 💜💛

Can any one that have used these or even use ovulation kits tell me when is the best time to use them what cycle day? I'm trying to conceive and only been using <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and my cm but nothing has happen so I decided to order a ovulation kit.. Feel free to comment! Baby 👶 bust to everyone trying🤞🙌🏽
