Before waiver of contraceptives and a shift to the calendar method of protection should know that a healthy woman can get pregnant any day – regardless of its date or of the position of the moon in the sky. Several relatively safe days do exist – it is two days before menstruation and two days after graduation. However the menstrual cycle can shift and change due to various stresses, taking certain drugs, diseases of the genitourinary system, etc., so no guarantee in this case can not be.
The use of the calendar method is only useful, if the woman's cycle is stable, otherwise, calculating safe days is virtually impossible. To schedule need to perform entire menstrual cycle for a year, during which it was not used hormonal contraceptive. With the constant onset of menstruation in the same period (assuming minimum deviation) it is possible to start the calculation of the safe period.
To schedule you first need to determine the length of the longest and the shortest menstrual cycle over the counting period. Then from the period with the minimum number of days subtracted by 18 and the result is a day in which the likelihood of pregnancy above all else. To calculate a safe day, we need to subtract 11 from the period of the cycle with the maximum number of days – so this will be the last date in which you need protection and which occurs after a few days, relatively safe for unprotected sex.
From the calendar method has its own characteristics. So, at irregular sexual life, the body can respond to each new sexual act, triggered by unplanned ovulation. The same often occurs when interrupted sexual intercourse – substances in male semen can induce ovulation, resulting in safe days before menstruation are not that. In other words, to avoid an unwanted pregnancy by using the calendar only if a regular sex life and a permanent partner.
To calculate the onset of ovulation and calculate safe days, woman should know the duration of your menstrual cycle.
Intervals dangerous periods in which a woman can get pregnant, usually approximately 12 days.
Advice 2 : How to calculate day of conception of the child
Unlike men, a woman is ready for fertilization only a few days a month. So if you are planning to conceive, you should calculate the auspicious days when this event most likely.
You will need
- - a test to determine ovulation.
The standard menstrual cycle of women lasts for 28 days. In the middle of this period ovulation – unfertilized egg leaves the ovary and in the fallopian tubes moves down to the uterus. In the tube most often does the meeting of egg and sperm and then the zygote moves into the uterus and attaches to the bottom of it.
In order to establish the date of conception of the child, you should know your cycle. Just divide the entire period from the beginning of one menstruation to the beginning of the next half and you will get a date for the start of ovulation.
Another way of calculating the optimum day for conception is a daily measurement of basal body temperature (temperature in the rectum). Every morning, waking up and not getting out of bed, insert the tip of the thermometer into the rectum. You can also measure the temperature and the vagina. The thermometer should be kept seven to ten minutes. Before ovulation the temperature does not exceed 37 degrees, and after the release of an egg, this figure increases. The first day, when you have a fever, is best for conception.
To determine an auspicious date for the conception of the child, based on observations of vaginal discharge. For a couple of days before ovulation, thick and sticky discharge becomes transparent.
Easily determine the day of conception of a child can be by purchasing in a drugstore the test for determining ovulation. There are two types of such tests. Some define the release date of the unfertilized egg from the ovary, based on changes in the composition of saliva, the other changes in urine composition.
Keep in mind that the egg remains viable for days, and sperm for two to three days. Therefore pregnancy can occur not only on the day of ovulation. This ability lasts for 6-9 days.
Advice 3 : In what period after a month you can get pregnant
The female body is ready for pregnancy in the undisturbed menstrual cycle once a month. The day is the time of ovulation of the egg. To know the right day for conception, you can use the calendar or the basal temperature measurement.
To calculate what days after your period there is a possibility to get pregnant, use the calendar of your menstrual cycle. If you mark the first day of menstruation every month, then you will not be difficult to calculate the duration of the cycle. Count the number of days from one mark to the other throughout the year. When your body works correctly without hormonal disruptions, you get the same figure in each period. Divide this number in half and find out the day of ovulation. For example, counting in perfectly regular cycle that is 28 days date of ovulation, you'll receive a 14 day.
Labeling is favorable for the pregnancy period in the calendar, fill in before and after ovulation for five days. It must be done because it takes into account the viability of sperm that were in the female before ovulation. Male cells are able to fertilize the egg in two days (and according to some sources even 5 days) after intercourse. Also keep in mind that in the body hormonal changes due to nervous shock, experiences, taken drugs, diseases, and many other factors, so the ovulation can move for a few days from the marked date.
If you have irregular menstrual cycle and are hormone disorders time of ovulation calendar method to install almost impossible, and must resort to other ways.
To determine the time of ovulation will help change the basal temperature. To define it - every morning before getting out of bed, measure rectal temperature. Immediately after menstruation, basal temperature less than 37°C, and more precisely, 36.8 - 36.9°C. the Egg is released from the follicle when the temperature reached 36.4 - 36.6 °C. After the ovulation the temperature rises above 37 °C. Knowing the day of ovulation, take the appropriate action: advance avoid sexual intercourse, when unwanted pregnancy, because the sperm retain the function of fertilization to 5 days in your body, or use the day of ovulation if you desire to have children.
After ovulation, the lifespan of the egg about a day – in this time and pregnancy. However, there are times when one menstrual cycle releases two eggs from different ovaries or after discontinuation of hormonal contraceptives they released a few, so the days of likely pregnancy increased.
To determine favorable days for pregnancy can be a special test strip ovulation. They determine the increase in the level of luteinizing hormone in the urine. Start using the strips every day immediately after menstruation, preferably at the same time. A positive test will show two bars, and you will know exactly the day of ovulation, the period when there is maximum probability of getting pregnant.
From unwanted pregnancy contraception use protection, please note that the calendar method is very unreliable.
If you want to become pregnant in the auspicious days, consider the fact that in daily intercourse sperm motility is reduced.
