Predicting Ovulation >> Free Ovulation Calendar

Use it to Pinpoint the Best Time To Get Pregnant!

It’s common knowledge – identifying when you ovulate is one of the keys to becoming pregnant. To this end, we’re pleased to provide you with the free ovulation calendar below; it’s a simple online tool you can use to plug in your cycle dates and receive a general estimate of when ovulation might occur.

But as you probably already know, there’s more to accurately predicting ovulation than simply plugging numbers into an online tool. Reliable ovulation prediction requires an analysis of your own body’s hormones – not just cycle dates. So what is the best way to determine your "peak fertile time”…?

5 Best Ways to Determine When You Ovulate – Your “Peak” Fertile Time!

#1: Ovulation Calculator: Use the ovulation calculator below to get a basic idea of when ovulation might occur based on your cycle dates.

#2: Ovulation Tests: Identify your “LH” surge using urine-based ovulation tests. (The “LH surge” is the dramatic rise in luteinizing hormone that occurs just prior to ovulation. Your LH surge represents the optimal time for having babymaking intercourse.)

These tests are easy to use, they’re affordable (just $0.60/test with free same-day shipping), and they’re 99.9% accurate in measuring the level of LH (luteinizing hormone) present in your urine.

#3. Saliva Ovulation Monitors: Use a saliva-based ovulation monitor, like Fertile Focus, to identify your estrogen surge. Similar to the LH surge, there is an increase in estrogen levels prior to ovulation. Using a simple saliva ovulation monitor (it looks just like a little tube of lipstick), you can view distinct patterns that appear in saliva that reflect this hormonal shift just prior to ovulation.

The best part about the saliva ovulation monitor? It provides an "advance notice" of ovulation, it’s completely re-usable – there’s nothing else to buy, and it at just $25 with free shipping, it’s a solid value.

#4. Fertility Monitors: Buy a full-fledged fertility monitor, like the Clearblue Fertility Monitor or the OvaCue. These are feature rich electronic instruments that measure urine and saliva, respectively, to provide you with a crystal clear, unambiguous indicator of your fertile status. They’re not cheap, but they do provide the wonderful peace of mind that comes with applying cutting edge technology to your trying to conceive efforts.

#5. Basal Thermometers: Chart your basal body temperature. Using a basal body temperature thermometer, you can not only confirm that you have ovulated during your monthly cycle, but also anticipate when your peak fertile period will likely be in subsequent months.

Basal body temperature charting is a great way to become attuned to your body’s unique rhythm, and can be used in conjunction with any of the aforementioned techniques. A digital basal body temperature thermometer costs less than $10.

How to Use the Ovulation Calendar

To use the calendar, simply enter the first day of your last period (the first day of menstrual bleeding), your average cycle length, and the length of your luteal phase. The Luteal Phase is the period of time starting day after ovulation and running through the remainder of your menstrual cycle. If you do not know your luteal phase, leave blank (the ovulation calendar will default to 14 days).

The ovulation calendar program provides approximate dates for predicting ovulation, and assists in determining when to begin ovulation testing. Please visit our instructions pages for more on when to begin using ovulation tests during your cycle.

Timing Love-Making

Predicting ovulation is central to successfully conceiving a baby. On average, it may take a couple 6 months or more to conceive a baby, so accurately predicting your most fertile time of the month, and timing intercourse accordingly, will increase your chances of becoming pregnant!

Fortuitously, we do not need a crystal ball to anticipate our ovulation date. Using the methods of bbt charting - in concert with a trusty array of ovulation testing products - we can accurately predict ovulation several days before hand. Using a ovulation microscope or an LH ovulation predictor test, you can identify your window of peak fertility (12-36 hours prior to ovulation and the day ovulation takes place). Following intercourse, try staying in bed for at least an hour.
