Fertility & Period Tracker 14.0

The application is based on scientific research and aids in determining fertile days of the month, allowing users to either achieve or avoid pregnancy. By inputting the date of the last period, the application provides information such as the date of the next period, the best days for conception, the ovulation day, and when to avoid pregnancy.

The default gender prediction method utilized in the application is the popular baby gender prediction method, which is based on the widely-spread theory by Landrum Shettles. Additionally, the application supports a scientific baby gender prediction method based on the research conducted by Rodrigo Guerrero and statistical data from thousands of women.

Users have the option to change the gender prediction method in the "Settings" screen. It's important to note that neither gender prediction method guarantees accurate results, as they only slightly increase the chances of conceiving a specific gender.

Full Version

This version of the application provides access to various data including:

• The probability of getting pregnant on the current day or on any selected day.
• The probability of conceiving a girl or a boy using the selected gender prediction method.
• Chances of getting pregnant during the current menstrual cycle.
• Chances of conceiving a girl or a boy during the current menstrual cycle.

How to Use

To generate the menstrual calendar, users are required to input the following data:

• The first day of their last cycle (selecting the day and clicking on "Add").
• The average length of their menstrual cycle (adjustable in the "Settings" screen).
• The length of their luteal phase (most women can use the default value).

The application functions best for women with regular menstrual cycles, but the average cycle length is also a reliable way of predicting ovulation.
