The Ovulation Estimator Plu application, also referred to as the Menstrual and Ovulation Calendar app, is designed to aid couples who are actively pursuing a rapid pregnancy program or those seeking to conceive a child. This app is built upon a scientifically-proven formula for determining the fertile period. To efficiently calculate a woman's prime time for pregnancy, it relies on two critical pieces of information: the HPHT data (First Day of Last Menstruation) and the Menstrual Cycle duration. This application provides a high level of accuracy and success in pinpointing your fertile period, eliminating the need to manually sift through a traditional calendar.
