A very good way to find out when you are going to ovulate is with the use of a fertility calculator. Unlike regular calculators, fertility calculators are wonderfully cheap and natural way to track your ovulation is with a plain calendar and knowledge of your own body. Also, there are many helpful websites available online that will calculate this for you. All you have to do is fill in the blanks.

Many women have used fertility calculators when finding it difficult to conceive and have been successful! Believe it or not, a woman can only conceive 12-24 hours out of the month and usually the problem is simply bad timing.

So, how do you use a fertility calculator to get pregnant? Whether or not you decide to do it yourself with a calendar or use software available online, you will still need to know some very important dates and numbers. Most fertility calculators online ask you 2-3 questions and these questions are straight forward they must be accurate to calculate ovulation correctly.

You're most likely to be asked when your last period started, the number of days in your menstrual cycle and sometimes these calculators want to know information about your luteal phase.

Now, the way you get these numbers is quite simple. Get a calendar and write down the first day of your last two periods. Okay, start counting days from the first day of your last period until the day before your most recent period; this is the number of days in your cycle. This number can be anywhere from 20-45 days, with 28 days being the average.

Working out the details on your luteal phase isn't as easy. This is a term used by doctors to describe the days in your cycle after you ovulate but before your period. It should last 14 days if your cycle is the standard 28 days.

Don't worry if it sounds too difficult! The majority of online calculators require only the most basic of information, so if you find one that wants information you can't give, just move on to the next calculator.

Some people prefer to use a pen and paper to work out when they're ovulating. If this is you, and you're looking at your journal dates, you can count backward 14 days from the time your next period is going to start, and this will be your approximate ovulation date. This is not an exact science, so assume you might be fertile 2 days before and 2 days after that approximate ovulation date.

If you want to incorporate the luteal phase in your calculation, then monitor the daily changes in your cervical mucus as well as your BBT. These two basic pieces of information can really help the accuracy of your fertility calculation.

So now you know how to use a fertility calculator to increase your chances of getting pregnant. Keep reading, because in a minute, I'll share with you a link to a free fertility calculator that won't require you to enter information on your luteal phase.
