How Does the Fertility Calculator Work?

The Fertility Calculator uses well-established reproductive science to estimate key dates in your menstrual cycle. Here’s a breakdown of its logic:

• Ovulation Prediction: Ovulation typically occurs around 14 days before the start of your next period. The calculator uses your cycle length to estimate this date.
• Fertile Window: The fertile window spans approximately five days before ovulation and two days after, as sperm can survive in the body for up to five days, and the egg is viable for about 24 hours post-ovulation.
• Safe Days: Days outside the fertile window are considered less likely for conception, though not guaranteed for pregnancy prevention.
• Next Period: The calculator adds your cycle length to the start date of your last period to predict your next period.

The tool assumes a regular cycle for optimal accuracy but provides estimates even for slightly irregular cycles. For highly irregular cycles, consult a healthcare provider for more precise tracking.
