Fertility Awareness

In the book "Taking Charge of your Fertility," I was taught a concept that made me say "Duh, why didn't I try that sooner?" This method is called the Fertility Awareness Method or FAM. The FAM method is one of the most accurate ways to determine ovulation, when your period will arrive, what days to baby dance in order to conceive, and can even be used as birth control!! Since this site is dedicated to TTCers, I am not going to talk about using it as a Birth Control Method.


This post will help you break down charting so that is super easy to do and understand. Don't be afraid of the chart pictured below, it's honestly not as complex as it seems!!


If you are TTC or ever are planning to TTC, this is something I think every woman should know about.

All you need to chart is well a chart, and they can be found all over the place. You can chart online at www.fertilityfriend.com or just google "Blank BBT Chart". Here's one you can use: CLICK HERE

And you'll need a basal body thermometer (BBT). They make these in digital or in glass thermometers. This is the one I use (mine's blue and white though). The significance of a BBT is it's acurate to a tenth of a degree, so instead of getting 98 or 99 degrees, you get 98.6 degrees. These are found everywhere, walmart, walgreens, anywhere you'd buy a normal thermometer. Some say the glass one's are more accurate, but I prefer digital.
So here's how you do it: Every morning as close to the same time as possible BEFORE getting out of bed, pop the thermometer in your mouth and take your temp. Stay as still as possible, and make sure you leave the thermometer right by your bed so you don't have to get up and get it. Make sure you have atleast 5 hours of uninterrupted sleep to get the best results. So, record the temperature on a chart in accordance with the cycle day you are on (i.e., your are on cycle day 10 so plot the temp on a chart. Do this every morning! Once you get in the habit of it and chart everyday you're chart will look something like this:


Ok, so now woopdie doo you have a chart going for you. Now what the heck does it mean?? This is when you look for a few things. First of all, make sure the day you start your period is on the chart as Cycle day 1 (CD1). Some charts have places to put details about your period or any spotting you might have. This one doesn't have anything for mentruation details. Anyways, your temperature should remain low until ovulation. This person's chart has her temperature lower than 97.9 when all the sudden it jumps to 98.1. That is an increase of .4 degrees. Why? That means this lady ovulated on CD13. After Ovulation, your temps should stay higher than before. This is the Luteal phase of your cycle. A successful pregnancy and implantation requires ATLEAST a 10 day luteal phase, but most doctors advise having 12 or more days...which means 12 days after ovulation is when you would start your period. So keep taking your temps even after ovulation. If they are staying above coverline (The highest temp recorded BEFORE ovulation) that is prefect! In a normal, non-pregnant cycle, the temperatures will begin to drop a day or two and fall below coverline to begin a new cycle. If you are pregnant however, your temps will stay up atleast 16 days, and sometimes even skyrocket on your chart to a whole new degree. This is one way to know you are pregnant before you take a test. It is also a way to identify missed miscarriages (very early ones).

Now, using the FAM and charting you can't really "predict" ovulation... you can only confirm when it has already happened. So what's the point in charting? MOST women (and I use this term lightly knowing how "Most" tends to mean a very few when it comes to topics like these) ovualte around the same time every month, so after a few months of charting, you may be able to time your baby dancing around those times you've recorded in the past.

I am a firm believer in charting now. I couldn't believe that I had do much control and "insider knowledge" to this technique. If you want to know more check out www.fertilityfriend.com.
