How to find out about the pregnancy by measuring the basal temperature
used a method called "fertile phase of the basal body temperature change" for measuring basal body temperature. This method is explained by the fact that the various phases of the menstrual cycle have different temperature variations. This indicates that in these various phases of the cycle is defined by different levels of hormones that show temperature.

Instruction how to find out about the pregnancy by measuring the basal temperature
During the woman's menstrual cycle temperature is always increased (37.0 and above). During the first phase of the cycle (follicular) until ovulation low temperature of about 37.0 - 37.5 degrees. Before ovulation occurs, the temperature drops, and after ovulation once rises to 0.5 degrees (approximately 37.6 - 38.6 degrees). This increased temperature is kept until the next menstrual period. If a woman is pregnant, the menses will not, and fever will be held throughout the pregnancy.
There are some guidelines for the measurement of basal body temperature - The temperature can be measured in the mouth, vagina or rectum. - The temperature should be measured every morning in the same period of time without getting up out of bed and write performance immediately. The menstrual period is also recommended to continue to measure and record the readings. - You should also measure the temperature of not less than three hours after uninterrupted sleep. - It is recommended to measure the temperature with the same thermometer. - Be sure to observe all adverse factors (stress, depression, moving, sex, etc.). This later allows to decipher to understand why there were variations in the temperature chart. - It is necessary to record the thermometer once, to later do not forget about them. - It should be noted that the exact timetable must be at least 3 months to observe.
If the high temperature is maintained for 3 days longer than usual during the phase of the corpus luteum (such phase after ovulation until the next menstrual cycle is characterized by high temperatures - above 37.0 degrees), the probability of pregnancy is high.
If the first phase of the menstrual period is unstable and may fluctuate, the corpus luteum phase is very stable and is approximately 12-14 days. It is very important to follow the second phase, but not for all cycle.
Typically graph is divided into two phases: the first - low-temperature phase, and then, immediately after ovulation, rises steeply, and is called luteal phase (high temperature). If after the second phase, an additional temperature jump up (sometimes slow), the schedule becomes three-phase and the probability of pregnancy is high.
If there are 18 in a row of high temperatures, the pregnancy is likely.
