Charting Your Basal Body
Temperature
First things first...
before I begin.. In order to chart
your basal body temperature (Your body's resting temperature) You will
need a basal thermometer.
Here is what a digital (yes, you're going to want digital) basal
thermometer looks like and a few places where you can order them online!
Below THAT, I will explain the whooollee story behind charting your
basal temperature to see when you are ovulating!

SO,
this is how it all works.
I will use my own charts from
various months as an example to show you how you should organize your
own chart. (As you can see
on my chart, I use www.fertilityfriend.com. I would suggest
www.fertilityfriend.com for charting. It has very helpful tips and
tools and helps to accurately pinpoint your ovulation day.
FertilityFriend does all the work for you! You just take your
temperature for them!)
Here are some abbreviations you will need to know to help you read the
example charts!
1. Day - Day on a fertility
friend chart.. just means "Cycle Day"
2. CM - CM stands for Cervical Mucus.
3. CP - CP stands for Cervical Position
4. BD - BD stands for Baby Dance.
5. Ener - Ener stands for Energy
6. Stats - Stats means just
that... your stats!
7. Mood - Mood is of course...
what kind of mood you are in!
8. Test - Test just means
Test... you record your home pregnancy test (HPT) results there.
9. OPK- OPK means Ovulation Predictor Kit.. There you can record the
results of any Ovulation Predictor test you may have taken.
You should start your chart on
Cycle Day 1, which is the first day of your menstrual period, as seen
below. This is the first day that you have red flow (not spotting).
(Cycle Days are numbered on the fourth row from the
bottom in this particular chart.)

There are
a few guidelines that you should follow when charting your temperature
to help you get the best interpretation.
Take your temperature first thing in the morning before leaving
bed.. and after at least three hours of sleep! (Make sure to use a
special Basal Body Thermometer)

Take your temperature at the same time each morning.. or as close as
possible. Take a note of the time.
Record your data on your chart or a bedside
notepad as soon as possible after taking your temperature.

Continue to watch your temperature each day from the first day of your
cycle to the last. The last day of your cycle will be the day right
before your period begins again.
How will you know when you have ovulated?
That's easy!

Just continue to watch your temperature
every day..It should stay the same for quite some and then rise at
LEAST 0.2 degrees. If it continues to stay raised until your next cycle
begins, you will know you have ovulated. The temperature rise MUST be
sustained in order to confirm ovulation.
The BIGGEST advantage of charting your temperature is that it is the
only method that uses your Basal Body Temperature... and your Basal
Body Temperature is a critical fertility sign, the ONLY one that will
tell you definitively that you ovulated!!
The ONLY draw back to charting your temperature every morning... is
that you won't know you have ovulated until it has already happened.
So.. Ya wanna know WHY your temperature
rises??
Well,
after you ovulate the corpus luteum (the remains of the follicle that
released an egg at ovulation) produces progesterone.
Progesterone
causes an increase in your body temperature that can be observed when
you are charting your basal body thermometer and taking your basal
temperature up waking each morning. The increase in progesterone is
what allows you to see the temperature increase.
What if I can't take my
temperature at the usual time or I have another circumstance hindering
my usual temperature or temperature taking?
Circumstances
that may cause an odd or unusual temperature that doesn't look good on
you chart may be sickness, lack of sleep, fever, or a different waking
time. If you are using fertility friend, it is usually a good idea to
NOT discard temperatures because Fertility Friend will analyze your
temperatures for you and still be able to determine when you ovulated.
Only when a temperate is NOT accurate or stops you from getting a
reasonable analysis, should you consider discarding temperatures. NEVER discard
temperatures just to make your chart look pleasing to you.
Should I adjust temperatures
if I wake up at a later time than usual?
Most
likely not. Usually an hour or less won't make that much of a
difference. It may be more pleasing if you adjust your temperature as
far as your chart goes... but it will not be more accurate... and more
accurate results are more valuable when it comes to taking your basal
body temperature.
Tip: If you wake up in the
middle of the night and are certain you will be able to go back to
sleep.. try to resist taking your temperature. Taking your temperature
more than once only lead to confusion and loss of sleep. HOWEVER, if
you wake up in the middle of the night and are sure you will not be
able to go back to sleep, go ahead and take your temperature and use
that one in your chart.
Is it more important to take my
temperature at the same time or can I just take it after three hours of
rest?
Most
women will be able to take their temperature after three hours of rest
and get the same result they would have had they taken their
temperature at their usual waking time. This varies, however, from
woman to woman based on each woman's unique metabolism. You will only
be able to tell if this is okay for you after charting for several
cycles.
What if I have to get up in
the middle of the night almost every night?
If you
have to get up in the middle of the night and it is unavoidable like
having to take care of a small child, or having to go to the bathroom,
just do the best you can. Some women will notice a rocky temperature
pattern because of this and some will not. Try to take your temperature
at the same time each morning or choose a time that will be after you
have had the most sleep.
What if I work shifts?
Just
take your temperature after you have had at least three hours of sleep.
Try to take it at the same time every day. If you wake at a different
time on your days off, just take it and make a note of it on your chart.
What if I travel?
If you
travel within your own time zone, just make sure you have had three
hours of rest. Traveling should not have a huge impact on your
temperature unless you are traveling to another time zone. If you are,
your temperature should only be affected on the day of travel and the
day after. Then just continue to take your basal temperature at your
usual waking time according to the local time where you are.
What if I have a rocky or erratic
temperature pattern?
If you
have a rocky or erratic temperature pattern, you may want to review
your chart and try to think of any circumstances which may be causing
your temperature to be off. If
there are no circumstances, you may consider making sure you are using
a Basal Body Thermometer, or changing the batteries in it. Also, some
women cannot get a clear biphasic (means two phases.. in your case..
lower and higher temperatures) pattern taking their temperature orally
and may resort to taking their temperature vaginally. If you have tried
everything and still have had several erratic charts, you may want to
consult your health care provider.
Also if you
have flat temperatures, or no biphasic pattern at all, you may want to
change the batteries in or replace your basal thermometer. If it
continues to happen, consult your health care provider. You may not be
showing any ovulatory pattern.
***You may also
get a rocky temperature patter when you aren't ovulating or are
having a delayed ovulation. If you are taking your temperature
accurately and still are not seeing a clear ovulation pattern, then
this may be the case***
Will I get more accurate
results my taking my basal temperature vaginally?
Most
women are able to see a pattern easily enough by taking their basal
temperature orally. When temperatures are rocky and erratic, it is
usually to poor temperature-taking habits (especially not taking the
temperature at the same time) If you are doing as you should and taking
your basal temperature at the same time every morning and still are not
seeing a clear pattern, you may want to try taking your temperature
vaginally. If you plan to do this... wait until a new cycle starts. Do
not change from oral to vaginal in the same cycle. This will disrupt
your basal temperature pattern since vaginal temperatures are typically
higher than oral temperatures.
To take your
temperature vaginally, just insert the tip of your thermometer inside
your vagina in the morning and record your temperature as usual.
Can I conceive on the day of
the temperature rise?
By the
time you see the temperature rise, you have already ovulated, which
means it is most likely too late to conceive that cycle. The best time
to have intercourse when trying to concieve is the few days before the
thermal shift in your chart. After charting a few cycles, you will
start to be able to predict or know when you will ovulate depending on
how regular your cycle is.
**Just so you
know**
Your
temperature will drop right before or right after your period arrives.
For most women it is before. If you see your temperature drop around
the time you expect your period, your period is still most likely on
its way and you are mostly likely NOT pregnant.
If it is before
you would expect your period, it is still too early to tell. Remember
you are looking for an overall patter. A single temperature doesn't
carry much meaning on its own in most cases.
My temperatures look to be
extremely rocky during my period. Why is this?
It is
not uncommon for temperatures to be rocky during your period or even a
bit higher than normal. Your hormones are just trying to return to
where they were before you ovulated. They normally don't take long to
level out. You should still be able to see a clear pattern and detect
ovulation.
Also, if you
see a temperature dip during your luteal phase (the time between
ovulation and your next period), it is not necessarily a cause for
concern. Remember, a single temperature doesn't carry much meaning
alone. You are looking for an overall pattern. If you continue to see
dips and such during your luteal phase, it may be to poor temperature
taking habits.
You may,
however, see a dip on the day of ovulation. Many women do see a dip,
but many do not. If you have the advanced warning of ovulation such as
this dip, take advantage of it and have intercourse that day. You may
not always see this dip, however.
What if I sleep with my mouth
open? Will this cause a problem with me taking my temperature?
If
sleeping when your mouth open happens only on occasion due to nasal
congestion or a cold, it should not have much of an impact on your
chart. Just keep on taking your temperature as usual and make a not of
the circumstances.
If you always
sleep with your mouth open, then maybe taking your basal temperature
vaginally would be the best route for you.
How much will my temperature
rise when I ovulate?
Normally,
you will be able to see a clear biphasic pattern on your chart after
ovulation has occured. The temperature increase may be as much as 0.4
degrees Farenheit and 0.2 degrees Celsius or your basal temperature
increase could be as slight as 0.2 degrees Farenheit and 0.1 degrees
Cesius. It may vary greatly. More valuable than the increase in
temperature is the overall pattern, though.
And also, basal
temperatures will normally remain roughly the same from cycle to cycle.
You shouldn't see much of a change there.
There are a few
small things that can change your basal temperature from cycle to
cycle. Some of these are seasonal changes, more or less blankets, and
having the air on or off. You should still be able to see a clear
pattern as these should not affect your temperature much at all.
Will I be able to tell by
looking at my chart whether or not I conceived that cycle?
Unfortunately
no. The only reason you may suspect pregnancy would be having your
temperature remain evelavated 5 to 10 days past the time you would
expect your period and obviously - not getting your period - .
Some signs of
implantation may be brief spotting, a second temperature shift of dip
about seven to ten days after ovulation. These can all happen, however,
with or without conception so they really aren't reliable signs of
conception at all.
Having a second
temperature shift after ovulation, meaning a triphasic pattern (three
levels of
temperatures) does not necessarily mean you are pregnant. Some women
with these charts DO turn out to be pregnant but many do not. ONLY
trust a positive pregnancy test.
There is also
no way to tell by looking at your chart if you MAY have released more
than one egg.
******* If you
are taking any fertility medication that may altar your chart, you may
want to speak with your physician about this. He can tell you
when to expect ovulation based on your own unique situation.*******
Can I chart while
breastfeeding?
Before
you get your first postpartum period, you may experience a long period
of time without ovulation. Charting during this time may be very
difficult. Just keep an eye out for other fertility signs such as
eggwhite textured cervical mucus and start charting then. At that time
you may be able to catch your first postpartum ovulation. Things will
be come much easier when you get your first postpartum period!
It is a good
idea to chart WHILE watching your other fertility signs such as
cervical mucus and position. Be SURE to read the other section of the
site that discusses cervical mucus and cervical position.
ALSO!! DON'T FORGET THAT IS IMPORTANT TO EAT A HEALTHY DIET! IF YOU
JUST DON'T FEEL LIKE EATING RIGHT =)), THEN MAKE SURE TO TAKE A GOOD
PRENATAL VITAMIN.. YES EVEN THOUGH YOU AREN'T PREGNANT YET!

CAUTION:

***CHARTING YOUR BASAL BODY TEMPERATURE TO DETERMINE WHEN
YOU OVULATE SHOULD NEVER BE USED TO AVOID
PREGNANCY. YOU MAY NOT HAVE INTERCOURSE AROUND THE TIME YOU OVULATE,
BUT HEALTHY SPERM CAN SURVIVE UP TO 3 OR 4 DAYS INSIDE A WOMAN'S BODY.
THIS IS NOT A RELIABLE FASHION TO
PREVENT PREGNANCY***
Some of the only reliable ways to prevent pregnancy are by using The
Condom, The Pill, The Shot, The Patch, or GET FIXED! Just DO NOT use
charting!
