so I've been reading some of these successful stories and some of you can get pregnant without this app. I believe this app is for women who can't get pregnant because of irregular cycles and things like that . but I'm here to tell you women that has irregular periods that think you can't have kids, it's possible my boyfriend and I have been trying for over 4 years been together for 6 years. I have a irregular cycles and my doctor put me on metformin back in June 2014 to help regulate my cycle and now my boyfriend and I are expecting our First and we can't wait til November. so best of luck to all and baby dust.
