What is a Fertility Calculator?

When planning a pregnancy, the first question that comes to mind is how to get pregnant. To answer this question, you have to determine the days in your menstrual cycle that offer best chances of becoming pregnant. The best way to determine these days is a fertility calculator.

A fertility calculator is a tool which determines the best days of your menstrual cycle when you can become pregnant. Using this information you can plan your chances of getting pregnant.

How Does a Fertility Calculator Work?

Based on the information about your last menstrual cycle and the duration of your cycle, the fertility calculator determines your ovulation dates and then gives you the days that offer maximum chance for a pregnancy.

How to Use the Ultimate Pregnancy & Ovulation Calculator

  1. Select the First Day of Your Last Period
    Use the calendar tool to click on the date when your most recent period began.

  2. Choose Your Average Cycle Length
    From the drop-down menu, select the number of days in your typical menstrual cycle (for example, 28 days).

  3. Click “Calculate”
    The calculator will automatically generate your estimated ovulation day and fertile window.

  4. Review Your Results
    Your predicted fertile days will be highlighted on the calendar, along with details about ovulation and the best time for conception.

Note: The tool is effective for those with regular menstrual cycles only and the results should not be used as a guide for contraception.
