My Open Letter to You

Getting pregnant is a journey, something I understand first hand - Founder, Phil Druce

My wife and I were unable to conceive naturally after a year of trying. It was frustrating. My friends around me were getting pregnant but we weren’t, despite our best efforts. Our journey to pregnancy was an emotional rollercoaster. It turned out, that no matter how much trying we did, we required medical intervention. We could have known this sooner had a tool like Ovulation Calculator existed. Today, I proudly let you know, I have two beautiful girls (twins) who enrich my life daily, in ways I didn't know were possible.

This is why I have spent so much time building Ovulation Calculator (formerly Ovulation Calendar) with my team, I wanted to create a tool and resource which could help couples throughout the world get pregnant naturally. See, 1 in 6 healthy couples struggle to get pregnant and around half of these occasions is due to the male partner. Getting pregnant however, could be as simple as getting the timing right. And, this is where Ovulation Calculator helps. An egg is released once each cycle (ovulation) and can be fertilised within only a 12-24 hour window. We accurately predict when you're ovulating and by knowing this, you significantly increase your chances of getting pregnant.

Ovulation Calculator asks you for a lot of data, personal, lifestyle and menstrual cycle data. We do this to boost the accuracy of the predictions. The more information you can give us, the more accurate your predictions will be. It’s that simple.

The information you provide also helps other couples trying to conceive. All your data is kept anonymous but we cross check all the data across all our users to identify patterns to increase our predictions further. On behalf of all our users, I thank you for this.

Thank you for using Ovulation Calculator, I wish you great success on your journey to pregnancy.

If you want to reach out I am available to answer any questions you may have or if you simply want to say hi, email me at Phil.Druce at OvulationCalculator.com
