Ovulation Calculator

An ovulation calculator helps you determine your fertile windows and the timing of ovulation based on your menstrual cycle. Here’s how you can use one effectively:

1. **Gather Your Cycle Data**: You will need to know the length of your menstrual cycle (the number of days from the first day of your period to the day before your next period) and the date of your last menstrual period (LMP).

2. **Input Your Information**: Enter this information into the calculator.

3. **Understanding the Results**:
– **Ovulation Day**: The calculator will estimate the day you are likely to ovulate, which is generally about 14 days before your next period starts.
– **Fertile Window**: It will also show the days you are most fertile, usually the day of ovulation and the days leading up to it.

4. **Regular Tracking**: To improve accuracy, track your cycles for several months to see any variations and adjust your calculations accordingly.
