Basal Body Temperature (BBT) and Ovulation Prediction.
Fertility Charting/Basal Body Temperature Charting allows you chart and predict ovulation based on calendar patterns, cervical mucus analysis, and changes in your body temperature. It is recommend that you chart your basal body temperature fluctuations using the free downloadable Zoe+Ruth chart here *inset basal chat* or put on page.
Basal Body Temperature (BBT) and Ovulation Prediction
During a woman’s menstrual cycle there are many changes that take place in a her body including an increase in body temperature at the onset of ovulation. During the first part of a woman's cycle, the body temperature is lower (97.0 to 97.5 F) With ovulation, the body temperature rises (this creates a more fertile environment for the fertilized egg) and remains higher until the beginning of a woman's next cycle. The temperature increase when ovulating is due to the hormone progesterone. A minimum temperature rise of 0.4 to 0.6 degrees F can be measured - and this change will last through the duration of the menstrual cycle.
Measuring and charting each day's body temperature will give a pattern of temperature changes which will help pinpoint when ovulation has occurred and determine future patterns for predicting ovulation. A sudden rise in your thermometer reading reading means that you have just ovulated (not that you are about to ovulate). By measuring and charting, you can determine important patterns in your cycle that allow you to predict fertility in your future cycles. You can then track this against the dates that you pre predicted using the Zoe+Ruth Fertility Calculator based on your last period.
Because BBT charting allows you to determine when this temperature change takes place and the onset of ovulation, it is a very useful method in helping to get pregnant by understanding your menstrual cycle.

How to take your Basal Body Temperature
Your Basal Body Temperature can be taken orally with the highly accurate Zoe+Ruth Digital thermometer, an easy-to-read one-tenth degree increment (one decimal place, 98.6, 98.7, etc) thermometer which is recommended by most doctors.
Important: Your BBT temperature refers to a 'resting' or 'base' temperature. This means that your BBT needs to be measured prior to any physical activity, after at least three to four hours of sleep (so make it the first thing you do in the morning before getting up). Make sure that you read and follow the thermometer instructions on how to take your temperature - if you have any questions, consult your physician.
1. Taking Your BBT Temperature
Take your BBT temperature first thing each morning - as soon as you wake up. You should remain in bed (as physical activity can increase your temperature - even moving around) and avoid eating or drinking. Either insert the thermometer in your mouth or alternatively your rectum (which is recommended as the most accurate method to identify basal temperature and we advise to extend the measuring time by 3 minutes after the beep). Record the full reading displayed on the screen.
2. Charting Your BBT Temperature
Starting recording your BBT temperature on day one of your menstrual cycle (day one of your period) on the Zoe+Ruth Basal Body Temperature Tracker. First thing each morning, record your temperature. Plot each day's BBT on the graph. Your temperature rise may be gradual, sudden or in steps. The pattern may vary each cycle.
3. Predicting Ovulation
For most women, 96 to 98 degrees is considered normal prior to ovulation and 97 to 99 degrees after ovulation. By charting the differences with the Zoe+Ruth Digital Thermometer, you can track when ovulation has taken place. Commonly a rise of at least 0.4 to 0.6 degrees will occur at ovulation, temperature increases may be sudden or gradual in different women. Over time, charting your BBT will help you predict your ovulation period and therefore predict the best time for you to fall pregnant.
Note:
BBT charting only identifies when ovulation has already occurred. Charting is therefore important for predicting general patterns for predicting future ovulation. Examining cervical mucus is also a very valuable method to determine ovulation. As always, please consult your doctor with any questions or concerns you may have with falling pregnant.
IMPORTANT LIMITATIONS: This calendar uses only approximate prediction and cannot be used to schedule procedures, avoid pregnancy or anything where more accuracy would be required - use at your own risk. It is intended for educational use only. Please consult your healthcare provider for any health concerns.
