The basal body temperature (BBT) - a body temperature at rest. Track basal temperature useful to couples who are trying to conceive, or want to avoid it, because in this way to know when ovulation occurs. In addition, it helps to understand the physiological processes associated with ovulation and menstrual general.
Not all women ovulate begins exactly two weeks before the start of the following month. In reality, many women during the period between ovulation and the onset of menstruation (luteal phase) is shorter. To have time to infiltrate the fertilized egg in the uterine wall, this phase should last at least 10 days. If it is shorter, pregnancy can be difficult.
Tracking basal body temperature enough that determine the best time for conception?
No. Temperature trend will let you know only that ovulation has already occurred. The ovum remains viable for only 12-24 hours after the addition, as it enters the uterus. BBT rises in 1-2 days after ovulation, and by the time fertilization is unlikely possible. Therefore, in addition to measuring the BBT, it is necessary to follow the changes of the cervical fluid - it will help to determine the probability of getting pregnant are highest.
How to measure the basal temperature?
BBT is measured using a special thermometer. Measurements can be made in the vagina, rectum or armpit, but most women prefer to measure temperature in the mouth, because it is more convenient and faster. It is important to measure the BBT as soon as you wake up. To do this, a thermometer, a paper and pen to put next to the bed - so close that before they could easily reach. The first thing you should do when you wake up - to measure the temperature, so any movement caused its increase. Of course, it has raised a few tenths of a degree, but you are tracking and BTT, to celebrate such small changes. Carefully read the instructions in the package insert a thermometer. Typically, it contains detailed information about the correct use.
How does basal temperature during the menstrual cycle?
BBT slightly decreased in the first two weeks of the menstrual cycle, before ovulation - is associated with increased production of the hormone estrogen
Estrogen - the key to bone health
. Immediately after ovulation in large volumes begins to produce the hormone progesterone
Progesterone - norm and pathology
Which enhances BBT for several fractions of a degree. The temperature remains elevated until early next month.
How to make the schedule of basal temperature?
To do this, the easiest way to use a regular notebook into a cell. Start recording the temperature on the first day of the menstrual cycle
The days of the menstrual cycle: Four phases
- That is the day when they start menstruating.

How to beat stress? Create an oasis
, Feeling bad, taking certain medications.
Can you using basal body temperature to determine pregnancy?
Yes. No change in BBT time when you already should have started menstruating can be a very early sign of pregnancy. After fertilization takes place about a week before the embryo is embedded in the wall of the uterus. That is what the body perceives as a signal of pregnancy. Then the blood is ejected chorionic gonadotropin (hCG, a hormone, whose presence allows to establish a pregnancy), whereby the body temperature is slightly increased.
