About basal temperature
Basal temperature is measured in the rectum, in the mouth or in the vagina. Experts recommend this method to use for women with menstrual irregularities, difficulties with conception, pathologies of the reproductive system. The main purpose of such measurements is the determination of ovulation. Just note that such measurements can not be reliable and do not represent value, if a woman takes hormonal drugs - they radically change the work of the reproductive system.
In order to obtain reliable basal temperature, it must be measured at the same time. It is recommended to do this immediately after waking up in the morning, without getting out of bed. Then the indicators will be accurate. The results of daily measurements should be recorded - entered in a special table and schedule. Obstetricians-gynecologists recommend that women keep this schedule for three months in a row - so you can get objective data, especially if the cycle is irregular for a woman.
The duration of the basal temperature measurement is 7-10 minutes. The mercury thermometer must be removed from the vagina, holding it by the upper part. By the way, the basal temperature will be the same in the mouth, in the rectum, and in the vagina. But it is very important to measure it always in the same way (vaginally, rectally, orally). Also, data can not be accurate, if less than 6 hours have elapsed since the moment of intimacy.< h2> Pregnancy and basal temperature
Its measurement is necessary in order to determine the favorable period for the conception of the menstrual cycle, that is, ovulation. In the first phase, the temperature in the vagina does not exceed 36, 8-36, 9 degrees Celsius. It can be different, but the above indicator is the highest possible. Further, in the next phase of the cycle (luteal), under the influence of progesterone, the basal temperature values ??increase. They can reach 37, 1-37, 3 degrees Celsius. The luteal phase lasts for several days, and during this period, ovulation occurs. The egg leaves the ovary, it is ready for fertilization with a sperm cell. And if a woman plans a pregnancy, it is necessary that an unprotected sexual intercourse takes place during this period, when the temperature in the vagina increased.
A few days before the next menstruation, the temperature drops again, they drop to the original 36, 8-36, 9 degrees. If, on the eve of the menstruation, the woman continues to fix them at a level above 37, then this is likely to be an indication that the conception has occurred.
Recall that the increase in basal temperature during ovulation is due to hormone progesterone. If a female ovum is fertilized at this time by a male, the progesterone production continues. This is necessary to support the development of the fetus. Further, after the fourth month of pregnancy, the temperature in the vagina begins to fall. They fall below 37 degrees, as the amount of the above hormone decreases. Then there is no point in fixing the temperature data.
Note that the basal temperature can tell about the unhappiness in the course of pregnancy. So, when frozen, it drops by 0, 8-1 degrees. And this, again, is due to the fact that the fetus dies, and consequently stops producing progesterone.
If a woman finds a drop in basal temperature in the first trimester, she needs to see a doctor. Perhaps this is evidence of a threat of miscarriage that can be stopped. Also raise the basal temperature to 37, 7 degrees. Sometimes its indicator can reach and 38 if the pregnant woman has begun inflammatory process.
So, basal temperature helps to accurately determine the periods of ovulation in usual women, and in pregnant women - abnormalities of gestation.
