Basal Body Temperature: Basal Temperature is the normal body temperature of a healthy person immediately upon awakening in the morning. In women, this temperature normally rises after ovulation due to hormonal changes. Thus, a temperature increase near the middle of your menstrual cycle can indicate ovulation has occurred.
Identifying Ovulation Timing: Tracking your basal temperature can help you to identify ovulation timing. Temperature Tracking Charts are included to help you track your temperature for your menstrual cycles. By taking your temperature with the B-D Basal Digital Thermometer each morning throughout your cycle, a pattern usually becomes visible. This pattern, along with other indicators can help you determine the timing of your ovulation. Knowledge of ovulation timing can help you increase or decrease your likelihood of conception.
Seeking Professional Guidance: Remember that temperature fluctuations and other observations are only indicators of ovulation. Interpretation of such information requires medical knowledge and training. Providing your doctor with completed Temperature Tracking Charts can help in fertility diagnosis and natural family planning techniques.

I've been reading the complaints that people have and a lot of them aren't valid or easily solved. Here they are:
PROBLEM 1: This thermometer can't be used as a basal thermometer or to track fertility because it doesn't record to the 1/100th (like 97.39) of a degree.
Answer: FALSE!! Tony Weschler, states in her latest edition "Taking charge of your fertility", a groundbreaking book on the subject of the Fertility Awareness method (and in turn NFP)--just look at the reviews on it here on amazon, on page 76 "Also, it is imperative that it be accurate to within 1/10th degree F. (for example, 97.4), BUT DO NOT USE THOSE THAT MEASURE TO WITHIN 1/100TH of a degree (for example, 97.47) since the latter are unnecessary and confusing." (emphasis added)
PROBLEM 2: The beeps are WAY too loud. They annoy me and wake up my spouse.
Answer: I personally don't find them to be too loud and neither does my husband, but if you do, on the back of the thermometer there is a small hole for the sound. When you're taking your temperature. Simply take your thumb and lay it straight down the back side of the thermometer while it is in your mouth, so that the hole is covered up. I found that this will SIGNIFICANTLY decrease the volume to a quiet, muffled, beep. You can even wrap your index finger around the top part of the thermometer (where it says BD) to give your your thumb some more resistance to press up against, muffling the sound some more.
PROBLEM 3: The back light doesn't come on when it's done taking my temperature.
Answer: When it's done taking your temperature, press the button to turn off the thermometer. The back light will turn on again, revealing your temperature before it shuts off.
PROBLEM 4: For the memory recall feature, the reading doesn't stay on long enough for me to be able to record the reading, and then it is erased.
Answer: When you turn the thermometer on, your last temperature will be displayed for about 4 seconds. If you turn the thermometer off again before it starts taking a new temperature (when it starts to flash), your temperature will actually still be stored on the recall feature. So when you turn it on again next time, it will still be there and continue to be there however many times you do this. Also if the 3 seconds you had before you pushed the off button weren't enough for you to see your temperature, you'll notice that you'll get an extra 5 sec's to read your temp when you press the off button before it finally shuts off.
I hope this helps!
What good is a thermometer that isn't accurate?
That being said, I did like the beeps that tell you it's working, the back light, and the memory recall. If it were accurate I would like this thermometer.
I love Amazon and have had great experiences however, in this case, I would basically lose money to return this defective item because for some strange reason I'm responsible for the return shipping costs. I could see that if I just didn't like the product but we're talking about one that is completely useless at this point.
Don't waste your money here! Go to your local drug store and buy one that you can return. Hopefully you'll have better luck!
My one complaint is it beeps the whole time its taking your temperature. If you are getting this for ovulating, you know that you have to take your temperature FIRST thing in the morning (preferably before you get out of bed). I wake up for work before my husband so I don't really want to be laying in bed while this thermometer beeps continuously and annoying the heck out of him... So I end up just taking my temperature in another room after I get up.. which makes it less accurate.
So if it didn't do the annoying beeping I would have given 5 stars. For someone tracking ovulation, it really is a hindrance to have to get a less accurate reading just because the darn thing won't stop beeping.
