Everything You Need to Know About Fertility Charting

Charting your fertility cycle is one of the most efficient ways to determine your best time to conceive.  Using this three-pronged approach can help you know the absolute best time to try to make a baby:

The Basal Body Temperature

Charting your basal body temperature (BBT) requires more than just taking your temperature every morning.  It requires getting to know your body and understanding the very subtle changes that occur right before, during and after ovulation.

In order to get an accurate reading be sure to:

  • Use a digital basal body thermometer to help you record the very slight variations in temperature
  • Begin recording your temperature on the first day of your menstrual period.
  • Be sure to use a thermometer that was shaken down the night before
  • Do not get up, go to the bathroom or exert yourself in any way before taking your temperature
  • Record your temperature on a chart as described below
  • Record any reasons for a higher temperature (cold or flulike symptoms; stress; sleepiness, etc. This could be important should you notice an unusual spike in temperature.

The absolute best way to chart your BBT is to use a series of connected dots from day to day. This will let you quickly see any rise in temperatures. This is important since your body tends to heat up as progesterone levels increase due to impending ovulation. A prolonged rise (over a few days) should indicate that ovulation is taking place.

Some of the things that would indicate a high fertility period include:

A Sloping Rise: Sometimes a gradual incline is all that is needed to indicate ovulation. This usually happens over a 3 to 4 day period.

A Slow Rise: Similar to a sloping rise, a slow rise may be indicated by a steady shift of temperature in small increments of one tenth of a degree Fahrenheit over 4-5 days.

A Fallback Rise: easier to notice but harder to understand, the fallback temperature rise pattern spikes abruptly and then is followed by significant dip before rising again and staying high until the next period.

A Staircase Rise: When the BBT rises in astaircase pattern, it goes up and then down several times before settling at an elevated level.

Cervical Mucous

Cervical mucous is vital to nourishing your partner’s sperm and guiding it along its journey. That is why your cervical mucous changes as ovulation draws near. As ovulation approaches your cervical mucus will go from strong thick and slimy to thin and stretchy. The best way to test it is to try and stretch it between two of your fingers. You will notice at some point the mucous becoming extremely stretchy. This is your most fertile time and is usually experienced about 11-16 days before your bleeding time. Of course, if you have irregular periods or an oddly time ovulation, it could happen some other time. That is why charting your mucous flow can be so helpful in figuring out your most fertile time.

There was one client who tried for two years to get pregnant. Desperate to conceive she visited a fertility specialist who ran a few basic tests and couldn’t find anything wrong. Before starting any invasive therapies, he asked her to chart her cervical mucous. What they discovered was that she ovulated on about day 8, which is extremely early when compared to the average woman. The result: she was simply missing her fertile time. Within 2 months she was pregnant! Her infertility was solved that easily.

If your cervical mucous is scant there are some natural cervical mucous enhancers that you may want to try out.

Interpreting Your Graphs

The third step to charting your personal fertility signs is to interpret the graphs you have made. Take a good look at your temperature charts over a 3-5 month period. Do you see any patterns? You should notice your temperature taking on some sort of common pattern whether it is a slow rise in temperature or quick spike. Note on what days those rises occur.

Now look at your calendar or note card where you recorded the changes in your cervical mucus. Look to see on what day or say it was at its thickest and scratchiest point.

Do these days match your high temperature days? Once you find where the two intersect month after month you will know exactly when you ovulate.

Now, what if your periods (and ovulation) are not predictable? It may be a bit more difficult, but you can use these charts and signals to tell you when ovulation is about to occur. Simply take note on a day to day basic whether you temperature rises along with your mucus thickening and act accordingly.
