When asking yourself how to get pregnant fast we recommend that you visit your doctor before you start using WOOM to calculate your fertile days or keep track of your ovulation cycle 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 a machine-learning algorithm that calculates your fertile days and daily chances of pregnancy based on the information that the user provides about her menstrual cycle and sex life. This will appear in a fertility calendar marking the days of your fertile window and ovulation cycle.

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

You will also be able to see the approximate chances of pregnancy for each fertile day marked in green.

Additionally, WOOM has a community of future mothers with whom to communicate to share advice, experiences and doubts about trying to get pregnancy, lifestyles, ovulation cycles, sexuality, chances of pregnancy, fertility days and menstrual cycles.

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

Was using another well known app for 8 months which had my ovulation late by a week. Used this along with clearlue ovulation tests for a month and I am pregnant 🙃

The registration has you put in your dates of your last period, but the calendar doesn't go back far enough! If you started your period late in the last month and haven't started this month yet, you literally can't sign up for the app without putting in false data. The rest of the app sounds nice, but unfortunately the registration process needs work.
