Before you start using WOOM to calculate your fertile days or keep track of your ovulation cycle, we recommend that you visit your doctor's office. WOOM will help you understand your fertility better and optimize your daily chances of pregnancy, but it does not replace medical instructions or regular appointments with a specialist.

WOOM works through an algorithm that calculates your fertile window and daily pregnancy odds based on the information that the user provides about her menstrual cycle and sexual life. This will be shown in a fertility calendar that marks the days of the fertile window and your ovulation cycle.

The calendar has three colors that indicate the time of the month according to your cycle: green represents the fertile days; pink represents the days of your period; and gray represents the follicular or luteal phase (the days when the chances of pregnancy are almost zero).

In addition, you will also be able to see, for each of the fertile days marked in green, the approximate daily odds of pregnancy.

Additionally, WOOM has a community of future mothers with whom you can consult and share advice, experiences and doubts about pregnancy search, lifestyle, ovulation cycle, sexuality, pregnancy, ovulation and fertility tests.

Join the community of thousands of women who have achieved pregnancy by knowing their fertile days with WOOM. Are you in?
