There are many ways to keep records of your fertility cycle, but what I love about FF most is the information tidbits they provide. I grew up in a culture that did not openly discuss sex, and the majority of advice for getting pregnant was "simply stop using contraception." With FF, however, I get a very specific scientific breakdown of the signs your body displays during different phases of fertility, and when your chances are best, and its been *incredibly* helpful. I have so much more confidence in trying to conceive now that weve decided to start a family. If youre looking for natural contraception, the same principles apply, just in reverse. Fantastic tool (and no tech glitches, app works great.)
