Choose your
Baby's Sex
with up to 95%
Success Rate!
The Fertility Calendar will predict the sex of the baby you are most likely to conceive for each of the 5 days when you have the highest chance of becoming pregnant in each period cycle. For each of the 5 days in a period cycle, the projections will identify the days you are most likely to conceive a boy or a girl or if it is 50/50. The 50/50 means that your biological rhythms are not in a phase where the sex could be determined. Recommended for women having very regular cycles.
