>> SCIENTIFIC & MEDICAL BASIS:
Our prediction algorithms are designed based on peer-reviewed medical research and standard fertility awareness methods:
- Ovulation Calculation: Based on the Rhythm Method (Mayo Clinic).
- Fertile Window: Calculated using the "5 days before ovulation" standard (Johns Hopkins Medicine).
- Conception Probability: Probability models derived from the Wilcox study (New England Journal of Medicine).
>> IMPORTANT NOTE: Fem Cycle Tracker is for informational purposes only. Due to individual differences (e.g., irregular cycles, stress), forecasts may not be 100% accurate. It should be used for tracking, but NOT as a method of birth control/contraception.
