Use of a fertility calculator

A fertility calculator is a useful tool, which is used to identify the day that a woman is next going to ovulate and therefore when she is going to be most fertile.

Introduction

A fertility calculator is a basic tool that can be found and used for free online. All it requires is for you to enter some simple information and it will do all of the calculations for you and then provide the day on which you will be most fertile and therefore most likely to conceive. For those people who don’t want to wait for many months to conceive the device can prove to be invaluable as knowing the time that you are most likely to conceive can massively increase the chances of doing so. Ovulation only lasts for approximately 1 day and in some people it is a matter of hours so knowing exactly when this fertile period is going to occur can be essential for some people.

How a fertility calculator works

The device is fairly simple and only requires some basic information in order to provide accurate results. The details that the fertility calculator should ask for include the date that your last period started, the length of your cycle and the approximate length of your luteal phase. You may not remember all of this information off the top of your head but if you keep regular notes in a daily journal or mark the dates on your calendar then it should be simple enough to provide the necessary details. Counting the days between each period will give you the results. The luteal phase is harder to work out, as it is the second half the menstrual cycle, starting at the days of ovulation and ending anywhere from 10-16 days later. It is not always possible to tell when you are ovulating so this information is not so easy to provide. Fortunately not all fertility calculator devices ask for this information. The simplest ones require only the date of the start of your last period and then length of your cycle.

DIY

Although online fertility calculator devices provide accurate results, some people prefer to work out when they will be ovulating by themselves. In this case all you need to do is count backwards 14 days from when your next period will start. This will give you a rough date but it is not exact so you should take two days before and after and assume that you will be ovulating at some point during this 5 day period. For more exact results work out when you are ovulating by monitoring changes in cervical mucus and your BBT. This will provide you with your luteal cycle, which when added to the calculation will help to provide more accurate results.
