It can take several months of charting before you actually get to see any patterns and recognize what your body is doing. As well as it can take you a while to get into a proper routine so that you are consistent. It is not individual temperatures that matter, but the over all pattern that shows up month after month.
Your goal in temperature charting is to find the typical biphasic pattern in the daily plotting of temperatures so you can determine when ovulation occurred. For most women, 97.0 to 97.5 degrees Fahrenheit (36.1 to 36.3 Celsius) is considered to be a normal pre-ovulation basal temperature. A temperature increase to 97.6 to 98.9 Fahrenheit (36.4 to 36.6) will usually occur at the time of ovulation. This rise in temperature is usually only about 0.4 degrees Fahrenheit (0.21 degrees Celsius), but the rise could be as slight as 0.2 degrees Fahrenheit (0.11 degrees Celsius) or even less in some cases. Use a quality thermometer and carefully document on your fertility chart. Make a point of using the same thermometer throughout your charting (at least throughout each chart), if at all possible. If it breaks or the battery dies, and you need to make some changes, make a note on your chart. Noting the small, one-tenth degree difference can help you determine when you have ovulated. Typically, a rise of 0.4 to 0.6 degrees Fahrenheit (0.2 to 0.4 Celsius) will take place after ovulation. Your temperature will continue to rise 24 to 72 hours after ovulation, at that point it should level out, fluctuating some what until menses. Some people will see a fairly abrupt increase, while others will notice a slow gradual increase. Time will, and charting, will tell you how your body will react to hormonal changes. At the time of menses, your temperature will drop off to your normal follicular phase temperature. Some people will notice this just before menses, and be able to use it as a warning, others may not notice it as can be more of a decline instead of a sudden drop. The actual temperatures are not important; they are different from woman to woman. What is important is to check for the pattern of elevated temps that stay up for at least three or more days. If you are lucky enough to be pregnant, you should find that your temperature will remain high.
Careful charting of your BBT is the key to effective charting. If you are not pregnant, your temperature will reflect two phases (biphasic) during a cycle, three phases (triphasic) if conception has occurred. The first phase occurs before ovulation and is known as the proliferative or follicular phase, it is during this phase that the egg matures and develops. The second phase occurs after ovulation, or during the post ovulatory phase, and is recognized by the fact that temperatures are higher than the first phase. This second temperature phase is known as the secretory, luteal or corpus luteum phase. Many women experience a triphasic phasic pattern, with temperatures climbing approximately 0.30 to 0.40 degrees Fahrenheit ( 0.16 to 0.21 degrees Celsius) during the Luteal Phase. This third phase is a result of the presence of hCG when conception and implantation has occurred. It is crucial that you remember temperature charting can only tell you when ovulation has already occurred in the present cycle, but it gives you an idea of when it may occur in future cycles. It does not give you any concrete evidence of what is happening in the present cycle, until it has already happened. BBT testing is most effective when used in conjunction with other testing methods. Immediately before ovulation, your temperature may drop briefly. Remember that your temperatures often rise and fall, before a dip, this can make it difficult to know when the lowest point will be. It is important to realise that your lowest temperature may not be a result of pre-ovulation. If you are fortunate enough to notice this drop, and you are charting other indicators that support it, use it to plan your next (as in now) sexual encounter. Within 12 hours of ovulation, you will notice that your BBT will rise, this is a result of the increased progesterone released from the corpus luteum after ovulation. Your temperature should remain in the higher range throughout the luteal (post-ovulation) phase until the next cycle begins. When your temperature remains high for three days in a row, you can believe that your fertile period is over and the infertile time has begun. This increase will remain until you begin your next menstrual period. Another point of interest here is that your temperature will often drop just before menstruation, a heads up that your period is about to begin. There are always exceptions, you could be one of those people whose temperature does not drop until a few days into menses. Your temperature will stay elevated for 10 to 16 days, until the corpus luteum regresses. At this time, unless there is a pregnancy, progesterone levels drop dramatically and you get your period. You temperature should also drop at this time, but some people are known to have erratic temperatures during their periods. If you are pregnant, the temperature will remain high since the uterine lining begins to put out the needed progesterone instead.
While measuring your BBT can help you to pinpoint, or confirm ovulation, it is important to measure this fertility sign in conjunction with other fertility signs. Observing multiple symptoms allows for cross-checking, in case one signal is affected by outside factors. Charting your temperatures tells you when you have ovulated, but it does not tell you when you are going to be most fertile in the current cycle. Your fertile days are the few days proceeding ovulation and the day of ovulation. Once your temperature has shifted, it is too late to use your chart to conceive in the present cycle. But it can tell you if you managed to time sexual activity at your most fertile time, and when you are best to time it for future cycles. Confirmed ovulation dates, from previous cycles are used to predict ovulation dates of future cycles, if you display some sort of a consistent pattern. Charting your temperature, along with observing your cervical fluid, can give you great peace of mind. You can actually see if you read your other fertility symptoms correctly and if you timed intercourse well, than you can stop worrying about your fertility for the rest of the present cycle. After ovulation is confirmed, you can take a break from planned sex and just enjoy each other. Confirmed ovulation can reduce stress for the end of your cycle, you know when you can reliably expect your menses or a reliable test for pregnancy. If your charts are well done, and your cycles are ideal, you should see a biphasic temperature change that clearly shows ovulation. You want to see your temperature rise in a single, abrupt, shift that remains through the luteal phase. Don’t stress, if this hasn’t happened, Remember your cycles are as individual as you are so things may still be fine.
A number of factors may influence your BBT readings, be sure to note them on your chart:
Illness and infection, (with or without fever) can increase your temperature.
Certain drugs and medication (including some fertility medication, discuss with your Doctor before you start charting).
Alcohol (specially in large quantities), even in small amounts, can increase your temperature
Smoking has an impact on temperature and over all health (consider quitting if you want to get pregnant).
Emotional stress increases your temperature and is very difficult for us to control (we are all under quite severe stress when trying to conceive).
Physical stress, or excitement, can affect sleep patterns, increased activity levels increase heart rate and temperature.
Sleep disturbances means that your body temperature can drop down into the ‘basal’, or ‘resting, temperature (insomnia, night waking, upsetting dreams, poor sleep, etc.).
Changes in routines, waking time, length or sleep, etc. should all is documented.
Things that affect your over all body temperature such as an electric blanket or higher than usual room temperature can all increase your ‘resting’ body temperature.
Low thyroid function should be ruled out first in infertility because it is probably the easiest cause of infertility to treat. Not only is WTS easy to treat, but it has the added bonus of being reversible. It can be persistently cured. People can remain improved even after the treatment's been discontinued.
Patients with low body temperatures and low thyroid symtpoms may benefit from T3 therapy for WTS and may be able to conceive when all else has failed.
Circle the appropriate temp for the appropriate day and log all other indicators for that day. Draw a line going from your first charted temp to your second charted temp, from your second charted temp to your third and so on. This will give you a clearer picture as to the rises and or falls within your cycle. Occasionally you may get an out of the ordinary temperature read - you may be ill, stressed, did not get enough sleep, had alcohol the night before....these temps should be logged but do not connect them to the previous day or the day after - the reason for this is they are not a true temp and may cause confusion in reading your chart. Remember to make a notation as to the cause of the unusual temperature.
