Using these principles, the calculator determines:
- Estimated conception date

- Expected due date

Practical Example of Using the Tool
Example 1: Planning Pregnancy
A woman enters:
- LMP: 1 March
- Cycle length: 28 days
The tool estimates:
- Conception date: around mid-March
- Fertile window: a few days before and after ovulation
- Due date: approximately 6 December
This helps her identify the best time to try for pregnancy and prepare accordingly.
Example 2: Pregnancy Tracking
A user already pregnant wants to estimate their due date:
- LMP: 10 January
- Cycle length: 30 days
The calculator shows:
- Estimated conception date: late January
- Fertile window: mid to late January
- Due date: mid October
This helps in planning prenatal visits, diet, and lifestyle adjustments.
