Currently, there are a huge number of contraceptives available to help prevent unwanted pregnancies. But among such a huge assortment, some couples can not choose a suitable remedy. There are several natural ways to protect against an unplanned pregnancy. One such means is the calculation of safe days, in which there is no threat of an unwanted pregnancy. Many couples prefer this method, although it is not reliable, but it does not carry a strong danger.
To successfully apply this natural method of contraception, you need to know how to calculate safe days for sex. There are some ways of calculating not dangerous days during which one can avoid unplanned conception. These methods are different in the degree of probable reliability and require accuracy, care and accuracy of calculations. To calculate safe days, a calendar method for calculating the fertility rate is used. In addition, such days can be traced using laboratory tests of mucus taken from the cervical canal, and also by measuring basal temperature.
Ovulation is responsible for the process of conception. Approximately fourteen days after the onset of menstrual bleeding a woman begins ovulation. The normal established menstrual cycle of the female body goes twenty-eight days. During this period, from the eleventh to the thirteenth day of the cycle, the egg is formed and released. It is necessary to remember the ability of spermatozoa to remain viable and energetic for seven days after they have got into the woman's body, thus conception may probably occur. It is necessary to abstain from sex from the eighth day of the menstrual cycle on the twentieth day. For the exact definition of dangerous days, you can apply the formula - the length of the longest menstrual cycle in days, we take eleven, we get the final day of the stage of the active ability of the body for conception; is taken as the basis of the calculation of the shortest period of the menstrual cycle in days, we take eighteen and get the start of the days when probable conception may occur. Menstrual cycles for calculation are taken for the last six months.
The stage of maturation of the egg can be calculated using a graph in which the basal temperature is fixed. A conventional thermometer is used. Basal temperature data are obtained by carefully inserting the thermometer into the rectum, without getting up from the bed, trying not to show activity, in the morning hours when you wake up at the same time. The thermometer in the rectum should be held for five minutes. The summary data is written to the notepad as a table. In the first half of the beginning of the menstrual cycle, the temperature is 36.3-36.5 ° C. Increasing the temperature to 37 ° C or higher is an indication of the onset of ovulation. This elevated temperature lasts until the end of the menstrual cycle. It should be borne in mind that a mature egg retains its viability for two days, so the second and third days after raising the basal temperature can be safe. But it is better to sustain a pause, because The egg has the opportunity to live for some time.
The characteristics of mucus taken from the vagina can show the presence of a safe period to prevent unwanted pregnancies. During the period of ovulation, the level of estrogen is significantly increased and due to this influence of hormones, the mucus becomes colorless and viscous. Such days for sex without contraceptives are not suitable, because the risk of conception is high. In case of violation of the hormonal background of a woman, the quality of cervical mucus may change and, therefore, such a method of calculating safe days is unreliable.
The most reliable way with which you can calculate safe days for having sex is a symptomatic method. This is a combination of all the above methods, i.e. careful fixing of basal temperature, daily quality control of excreted mucus and mandatory calendar recording of menstrual cycles.
