Stuck

Sorry I'm new to this app and my husband and I are trying for a baby. I was told by my 3rd cycle the chance is 68% that I should be pregnant if I use the <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation tracker</a> and my fertile days right. But what I don't understand is 3rd cycle. Does that mean after at least 3 months or what? I'm confused please help :)
