User Guide for Babyplan’s Due Date and Ovulation Test Calculator Wheel
With our Babyplan Due Date and Ovulation Test calculator wheel you can easily find out when to start using ovulation tests. If you’re already pregnant, the wheel lets you calculate your estimated delivery date.
Ovulation Test Calculator
When should you start using ovulation tests?
Before you start testing for ovulation, you must have an idea of when in your cycle you are most likely to ovulate. You can find this ovulation window easily using our ovulation test calculator wheel. All you need to know is the length of your menstrual cycle and the first day of your last menstrual period, and the calculator will tell you when to start testing for ovulation.
To set the wheel to calculate when to begin testing for ovulation
Watch the animation below. Wait approximately 10 seconds for the animation to begin.
- Rotate the inner circle so the typical length of your menstrual cycle appears in the window.
- Place the light blue arrow, which is an extension of the red line, on the date of the first day of your last menstrual period.
- The corresponding dark blue arrow will now point to the date when you should start using ovulation tests.
In the example above, if your cycle length is 28 days, and the first day of your last menstrual period was August 14, you should begin using ovulation tests on August 26th.
The ovulation test calculator wheel should only be used by women whose menstrual cycle lasts 21-36 days.
