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?

I was trying to get pregnant for 6 months and I felt like maybe there was something wrong with me or my husband but then I downloaded this app and I followed the period tracker for a couple months so that it could build some accurate data to predict when I was ovulating and finally I planned to conceive on my most fertile day they recommended and BOOM IM PREGNANT AND IM SO HAPPY , I am currently 5 weeks on the dot and I can’t tell you how happy I am !!!! Thank you so much woom and the women on the blog that would write their own personal struggles they really kept me going. It’s such a great app I recommend this to every woman trying to get pregnant. 👍👍👍👍👍👍👍👍👍

4 months of trying!

Hi! 4 months of trying here. I used an IUD for 2-1/2 years and then got it removed to try for our 3rd and final child. The period tracker and ovulation tracker was right on track!!! I did get a positive pregnancy test back in October but then had started my period about 6 days after having a positive. I am so excited to start this journey for the last time. I do plan to get my tubes tied in the end.

Congratulations, we are very happy for you and wish you the best in this new journey 💚💚

WOOM App Review by Jazzy

The only thing I didn’t like about the app was the BBT tracking or lack thereof. If there’s a better way to track it on this app,I never found it. There’s an option to put in your temperature but it only measures to decimal’s nearest tenth and I needed it to go measure up to the nearest hundredth. Also I couldn’t figure on my own how to get the temperature to F° instead of C°. Other than that, all good. The daily questionnaires were helpful and the display of your actual, percentage chance of getting pregnant were exciting to look out for!
