Natural family planning has been scientifically proven to be up to 98% effective if the techniques are followed correctly. Calculate future periods and ovulation on an easy to use ovulation calendar, select a natural family planning goal and receive related information.

What's more, the GirlPro mobile ovulation calendar employs techniques for baby gender selection. While the accuracy of the gender selection techniques are far less accurate (up to 80%) than the natural family planning techniques, it does help sway the odds in your favor just a little bit. These baby gender selection techniques were developed by the famous gynaecologist and obstetrician, Dr. Landrum B. Shettles, who is well-known for being the first doctor to attempt in vitro fertilization (IVF) and for his work as an anti-abortion activist, as well as for the invention of gamete intrafallopian transfer (GIFT).

Finally, even if you don't want to use GirlPro for natural family planning, it still serves as a very useful tool to predict future periods and avoid embarrasment.
