Within a month, some processes are constantly taking place in the woman's body. Everything revolves around an egg that is preparing to become a potential progenitor of your offspring. During its maturation, exit and further development, the hormonal background changes mainly. You experience mood swings, a change in the nature of vaginal discharge, changes in appetite, moods and many other reactions. Among other things, the basal temperature also changes. A woman does not feel these changes, but if she keeps a graph of basal temperatures, she sees that the indicators depend on ovulation. It is the moment when the egg leaves the ovary and is a certain starting point.
Normal basal temperature during pregnancy
From the third to the fourth day after the end of the monthly BT is in the range of 36, 5-36, 9 А C, C. Such a temperature regime creates optimal conditions for the maturation of the next in turn egg. Closer to the middle of the cycle (or rather, on the eve of ovulation, which all occur on different days of the cycle), the basal temperature drops sharply, so that it also rises sharply. However, this temperature fluctuation may not be, but there is a noticeable increase in the basal temperature in comparison with the first phase of the cycle - at least 0.4 А C, which is evidence of the onset of ovulation.
With the onset of ovulation, the basal temperatures rise to 37 А C and above (37, 2-37, 4 А C). In different women, these indices may not be the same, but in order for ovulation to take place, the temperature difference between the phases should be on average 0, 5 degrees.
The increase in basal temperature is the "work of hands" of progesterone, which is activated after ovulation in order to provide the most favorable conditions for the further life and development of the ovum.
If conception takes place, then progesterone will work further, keeping the basal temperature at elevated elevations. In the case of the "idle" yield of the ovum, the level of the pregnancy hormone will gradually decrease in favor of estrogen, under the influence of which the BT gradually decreases before the next monthly. During menstruation BT is quite low: the day before it ends, it is an average of 36, 3 А C.
It is possible to suspect pregnancy before the delay in the case when the basal temperature after the increase is kept at high levels for 18 days or more and does not decrease with the onset of the delay. Basal temperature during pregnancy before the delay will indicate conception, if it is kept at high marks for 3 days longer than usually began to decrease before menstruation. In addition, the occurrence of the third phase of the schedule indicates the high probability of pregnancy, when the increased BT after ovulation again increases at the end of the phase of the yellow body. If you observe a decrease in BT for one day during the period of its steady increase, then almost certainly one can speak about the onset of pregnancy. Experts call this phenomenon "implantation Westernization", which is accompanied by the release of estrogens and occurs on the day of the fertilization of the fertilized egg to the wall of the uterus.
How to measure basal temperature
The basal temperature during pregnancy before the delay can hint to a woman about the occurred conception one of the first among all the symptoms. However, in order to obtain reliable data, a BT schedule should be kept for at least 4-6 months in a row, without violating the baseline temperature measurement rules:
- Measure without getting out of bed and doing no sudden movements.
- The duration of sleep before measuring BT should be at least 6 hours (without night trips to the toilet or the kitchen).
- Always use the same thermometer to measure BT.
- Any factors that can affect the result of measurements (somehow transferred illness, stress, insomnia, sexual intercourse shortly before the measurement, reception of alcohol or medicines and others) should be noted on the chart.
Many of us are measuring BT just to get pregnant: while observing the data of the graph, they try to calculate the most favorable period for a fateful sexual intercourse. Although in fact the stability of the BT schedule is considered to be an indicator of female health and the state of its reproductive system as a whole. Therefore, such measurements gynecologists recommend to every mature woman.
