What is possible and not possible during the Nativity Fast?
In 2018, the Nativity Fast will begin on November 28. During this period, Orthodox believers prepare to celebrate Christmas...
The woman's body - complex mechanism. Even pregnancy can occur only during a certain period. And to find out which one, find out dangerous days for conception, and also learn to calculate them.
Pregnancy can only occur during ovulation. At this moment, a mature, viable egg emerges from the follicle, which can unite with a sperm, which will lead to the birth of a new life. But when exactly does this happen?
The period of ovulation occurs approximately in the middle of the menstrual cycle. That is, if its duration is 27-28 days, then the egg will mature approximately on the 13-14th day. But this does not mean at all that you can get pregnant only on this single day. Favorable or, on the contrary, dangerous period lasts for several days. The fact is that sperm can remain viable in the female body for 4-5 days. And the egg, matured and released from the follicle, lives only 24-48 hours. It turns out that the probability of pregnancy remains increased two days before ovulation, as well as for about 1-2 days after it.
There are several ways to calculate dangerous days for conception:
Even normal woman So-called anovulatory menstrual cycles may occur, during which the egg does not mature. But normally their frequency should be no more than once or twice a year. If ovulation does not occur for several months in a row, then this is most likely a symptom of a serious abnormality or gynecological disease.
Calculating dangerous days is not so easy, but if you know some features female body, then this will become possible.
IN modern world There are many methods of contraception (condoms, contraceptives and so on). However, some women prefer to calculate dangerous days for pregnancy after and before menstruation using other methods. How to do this and what factors can affect their reliability?
The menstrual cycle is divided into 3 main periods of dangerous and safe days:
Determining dangerous and safe days will require discipline and attention from a woman for some time. First you need to calculate the length of the monthly cycle. All calculations are carried out on the basis of cumulative data for 6-12 months. To do this, you need to keep a calendar, where you need to record the beginning and end of the cycle, the nature of the discharge (scanty, heavy), the duration of each cycle. Important condition– the cycle must be regular. The onset of menstruation is the first day of a new monthly cycle.
Once the number of days in the menstrual cycle is determined, dangerous days for conception can be calculated.
The most safe days after menstruation, the last day of menstruation and 2-5 days before the start of the next one are considered.
The chance of getting pregnant is quite high for women who have irregular sex life. The body may react to rare sexual intercourse with unscheduled ovulation. It can be triggered, for example, by substances contained in semen. Women who regularly have sex with a regular partner may not experience this.
Pregnancy in the first days of menstruation is unlikely. This is due to an unsuitable environment for sperm and embryo implantation.
However, in in rare cases Conception can still occur:
Pregnancy immediately after menstruation can occur for the following reasons:
Based on this, the calendar method is not a reliable means of contraception.
If small deviations are observed within 6 months, then the following calculations can be made:
If the monthly cycle continues:
When a woman has abundant bleeding end in 2-4 days - the dangerous period begins already on the 6th day of the new cycle.
To determine dangerous days, you need to measure your basal temperature rectally from the 1st day of menstruation every morning immediately after waking up, without getting out of bed. Based on the data obtained, a schedule is drawn up.
In the first phase of the menstrual cycle, the temperature ranges from 36.6 to 36.9 degrees. The temperature rises above 37 degrees after the release of a mature egg. If the temperature drops slightly (approximately this happens on days 12-16), this indicates the onset of ovulation and dangerous days.
Some errors may appear for the following reasons:
A fairly accurate means of determining the release of an egg. The line on the test appears due to the presence of the hormone luteotropin in the urine. Before the expected release of the egg, tests are recommended to be done every day at the same time. On the eve of release, the level of luteinizing hormone increases sharply, which indicates that the follicle will rupture in the next 2 days. At this moment, 2 stripes appear on the test.
Method ultrasound examination(ultrasound) is most often used by women who want to become pregnant. You must visit the ultrasound room from the 10th day after the start of your last period. Growth will be observed over the course of several days. dominant follicle in the ovary. When its diameter reaches 18-25 millimeters, an egg ready for fertilization will be released. In rare cases, follicle formation may not lead to ovulation.
The main sign of the onset of dangerous days and favorable period for conception, which the doctor sees on the monitor during the procedure is corpus luteum, located in the ovary without a dominant follicle, and a small amount of fluid behind the uterus.
This method is not 100% accurate, but most women who are sensitive and attentive to themselves can determine dangerous days by subjective sensations.
The most common are:
Women experience anovulatory cycles 1-2 times a year, during which it is impossible to conceive a child.
Such days can be identified by the following criteria:
To use the calendar to determine dangerous and safe days, you need to take into account that the calculation will be correct only if the following conditions are met:
Before and during menopause at a young age The menstrual cycle may change, making the calendar calculation unreliable.
Also, the following factors influence the change in the cycle, and, accordingly, the day of ovulation:
In a woman's menstrual cycle, dangerous and safe days can be distinguished. Dangerous days are those on which fertilization can theoretically occur, safe days are when the possibility of conception is completely excluded. Many women are interested in how to calculate safe and dangerous days. You can calculate your own ovulation calendar.
Let's look at some physiological basics. So, once a month a woman gets her period. The uterus is washed away by bleeding from the remnants of the endometrium and is renewed. Approximately 14-16 days after the start of menstrual bleeding, the period of ovulation begins (dangerous days for conception).
To determine on which days of the cycle neglect of contraception can lead to unwanted pregnancy, you need to accurately calculate the day of ovulation. During this period of the cycle, the egg matures and leaves the follicle. Its viability lasts about a day.
If during this period of time a meeting with a sperm occurs, fertilization and pregnancy can be expected. These are dangerous days for conception. The viability of sperm in the uterus is approximately two days. Therefore, you need to add four days before ovulation and four after and remember that there should be no unprotected relationships during this period.
Let's make an approximate calculation. With a 28-day cycle, ovulation occurs (normally) on the 14th day from the start of menstruation. That is, if your period began on the second of December, add 14 days, it turns out December 16 and is the day of expected ovulation. We add “insurance” days and get the period from December 12 to December 20. These 9 days are considered dangerous days for conception. If you have a regular cycle, you can use a regular calendar and different colors Color in the cells of expected ovulation and “safety” days.
How to calculate the onset of ovulation more accurately? In order to identify the day of ovulation, you can measure your basal temperature. That is, in the rectum or cervix. Basal temperature must be measured as soon as you wake up, without getting out of bed. In this case, it is advisable not to include bright light and it is best to keep the thermometer near the bed.
You need to insert the thermometer no less than five centimeters and in ten minutes you will get the result. On safe days, the basal temperature is no more than 36.9 degrees. And its increase to 37.2-37.6 degrees indicates the onset of ovulation. Usually in the middle of the cycle the temperature drops slightly and immediately rises. The day when the temperature is lowest before rising is the day of ovulation.
To draw the right conclusions, a basal temperature calendar should be kept for at least 3-4 months. It should be noted that with a viral or infectious disease It is necessary to monitor body temperature in the usual way. At elevated temperature body basal temperature chart will not be reliable. For clarity, you can build a personal graph or basal temperature chart. With its help, it will be easy to calculate the onset of ovulation and “dangerous days” will not be taken by surprise.
There are other signs of ovulation. For example, more liquid, water-like vaginal discharge. But this is for very observant women. In addition, the consistency of the discharge depends on the woman’s health.
Nowadays, women are often so busy that there is simply no time to calculate the calendar. An ovulation test will help. Modern and sufficient effective remedy to determine ovulation. When using it, you do not need to keep calendars and various diaries, or listen to your well-being and sensations.
You just need to buy a test and test it 10-12 days after the onset of your period. It acts based on sensitivity to the hormone LH (luteinizing hormone). It is produced in large quantities by the pituitary gland during the maturation of the egg. The body is preparing for possible fertilization. Urine is used for the test, just like for a pregnancy test.
When using the test three to four hours in advance, you should not drink large quantity liquids so as not to dilute the urine. You can also use highly informative digital test for saliva. This is the most accurate diagnosis, eliminating any error.
If a digital saliva test is used, you need to compare the obtained indicators (a picture similar to a frosty pattern) with the control ones. Such tests are most often used by women who are having trouble getting pregnant. Having sexual intercourse directly on the day of ovulation significantly increases the chances of conception and pregnancy development.
With two stripes, the most dangerous days suitable for conception have arrived. If the second stripe is weakly expressed, the follicle is preparing for the release of the egg. You should also take care of contraceptive methods. We must not forget that the test does not directly indicate that the egg has already been released; it reacts to a hormonal surge in the woman’s body.
You can use all methods in combination. It's more reliable this way. Keep a basal temperature calendar for several months to calculate the onset of ovulation. If everything fits, you can mathematically calculate the calendar of ovulation and “safety” dangerous days. You can use this calendar for quite a long time. Periodically, it is advisable to use a pharmacy ovulation test for control.
Do not forget that prolonged stress conditions, sudden climate change, and hormonal disorders in a woman’s body can lead to a delay in the onset of ovulation.
This method of contraception is more suitable for couples for whom pregnancy is not yet very desirable, but in principle possible. For couples who absolutely do not plan to have a child, it is better to choose a more reliable method protection from pregnancy.
What days are the most dangerous for pregnancy, when conception can occur? Every educated woman knows that she cannot conceive every day. It is possible to get pregnant only on the days of ovulation, when an egg is “born” in the ovary. Before and after this event there is no egg, which means there cannot be a child. However, in in this case Various nuances are possible. Let's talk about dangerous days for pregnancy, the accuracy of their calculation, and why women, even those who know their physiology well, still get unplannedly pregnant.
So, the female menstrual cycle is divided into three phases. The first one starts with the next critical days. In the first days of the cycle, 5-7 days, bleeding is usually observed. The dominant follicle in the ovary is determined, and hormonal changes, thanks to which it ruptures, and a mature egg, ready for fertilization, is released into the internal genital organs. This process is called ovulation. This is the second, ovulation phase of the cycle, which falls approximately in the middle of the cycle.
Immediately after ovulation, a corpus luteum appears in the ovary, which begins to produce the hormone progesterone. The endometrium is transformed and becomes favorable for egg implantation. And if fertilization of the egg occurs, and it exists only for a maximum of 48 hours, and more often 24 hours, then the level of progesterone remains high. This is expressed as tenderness of the mammary glands, as a rule. If conception does not occur, then shortly before the onset of menstruation, progesterone levels decrease. And these hormonal changes provoke endometrial detachment and the beginning of a new menstrual cycle.
Is it possible to get pregnant immediately after menstruation, say, on the seventh day of the cycle? Ovulation cannot happen that early. However, sperm have the property of not dying in the female genital tract for up to three days. Therefore, there is a small probability of pregnancy if a woman has a shortened menstrual cycle, its duration is less than the statistical average. Just over 20 days.
Well, according to most women, after menstruation, the days dangerous for pregnancy begin around the tenth day. And ends 2 days after ovulation. Thus, to avoid unwanted conception without using medically recommended contraception, you just need to learn how to calculate or determine ovulation. Ovulation has some pretty noticeable symptoms.
1. Copious, mucous discharge from the vagina that “stretches.” Similar to egg white. They are often found on toilet paper.
2. Minor bloody issues, stabbing pains in the area of the ovary. Injection in the ovary begins immediately at the “birth” of the egg. Well, spotting is a small detachment of the endometrium that occurs in response to a temporary decrease in hormones. It doesn't happen to everyone. They often go unnoticed due to their small numbers.
3. Increased libido. Sexual desire is on top level. This can be explained by some natural pattern. This ensures better fertility.
4. Increase in basal temperature. Its measurement is best done in the rectum. Be sure to do it in the morning, without getting out of bed and without making unnecessary movements. In general, in order to create your own conception calendar, that is, calculate online days that are dangerous and safe for pregnancy, you just need to enter the start date of your last menstruation and indicate the duration of the cycle. But by charting your basal temperature changes, you can get even more accurate data.
So, just before ovulation, a few hours before it, the temperature drops slightly, and immediately after it rises to 37 degrees or higher. At the same time, it remains elevated almost until the beginning of the next menstruation. And in case of pregnancy it does not decrease at all.
However, no calculation of dangerous days for pregnancy or otherwise safe days of the cycle provides 100% guarantees of accuracy. Often calculations and subjective feelings turn out to be erroneous, and an unwanted pregnancy occurs. It will be more correct and effective to use contraception approved by doctors.
To know when you can get pregnant after menstruation, you should study the woman’s physiology in detail.

Even during the period of intrauterine development, the female fetus develops ovaries, which remain immature until the girl reaches puberty - the age when fertilization of eggs leads to conception. The girls are starting menstrual cycle– periodic changes in the body that occur regularly and are aimed at conception.
The duration of the cycle for each sexually mature woman is individual, calculated from the first day of the previous menstruation to the first day of the next one and lasts 28 days, but can vary from 26 to 34 days.
The entire period is divided into 3 phases of development.
Having become familiar with physiology, theoretically it can be argued that the time of fertilization is limited to 1-2 days of the ovulatory phase. However, there are enough examples to refute this statement. So what are the chances of getting pregnant after your period?

It seems that everything is very simple: after calculating the days of ovulation, you can have sex before it, without thinking about the consequences, or after it - to conceive a baby. But if everything is so simple, why so many unplanned pregnancies or unfulfilled hopes?
When it comes to women reproductive age who do not suffer from specific diseases, we can say that you can get pregnant on any day of the menstrual cycle. It’s just that sometimes the chances of conceiving are very high, sometimes they are much less.
It is possible to get pregnant immediately after your period under the following conditions:
Based on the above, calendar method contraception in parallel with various methods determining the days of ovulation can be used by mothers during lactation or women who have mechanical and oral agents protection is contraindicated for health reasons.
To calculate which days after your period you can get pregnant and which days you cannot, you need to monitor your menstrual cycle for at least six months. It is understood that during this period the use of contraceptives will be excluded.

The calendar method of contraception takes into account the viability and activity of sperm entering the the fallopian tubes, for three, and sometimes more, days. With a 28-day cycle, fertilization of the egg is possible two days after ovulation, that is, from days 10 to 16. With a 30-day cycle, this period falls in the interval from days 13 to 18, etc.
If the cycle is regular, with minor deviations, we will use an ovulation calculator and calculate the days after menstruation when you can get pregnant.
Based on the example considered, we can conclude that the chances of getting pregnant fall during the period from the 6th to the 17th days of the menstrual cycle.
In the table in percentage It is indicated on which days after menstruation you can get pregnant:
Does this mean that we have found the answer to the question “on what day after the end of your period can you get pregnant”? Not at all!
The calendar method is not a 100% reliable method for determining the ovulation period, especially with an irregular menstrual cycle, the shift of which can be caused by factors such as stress, medications, various diseases, nervous breakdowns. This method is useful for determining the “fertile window” so that a couple who decides to have a baby knows how and when to get pregnant after their period.
There are other ways to precise definition, on what days after menstruation can you get pregnant.
Is it possible to get pregnant during menstruation or on the second day immediately after it? Let’s immediately make a reservation that sex during menstruation is associated with the risk of infection and further inflammation of the uterus and appendages. If sexual intercourse has occurred, then the conception rate during this period is extremely low, but this possibility should not be excluded.
All the most important things are here
It is possible to get pregnant during menstruation if:
Is it possible to get pregnant on the first day immediately after your period? What is the possibility of getting pregnant on the second or third day immediately after your period? Based medical practice it can be argued that conception during this period is not at all uncommon.
When can you get pregnant after childbirth if you haven’t had your period yet? Calculation of ovulation days can begin as early as two to three months after birth.
Contraception is not a guarantee breast-feeding, nor absence of menstruation. When it is resumed, the chances of conception are equal to the chances of non-breastfeeding women.

Despite the absence visible reasons, many couples cannot conceive either the first time or after months of unsuccessful attempts. This may be due to some negative factors.
Besides, ethnoscience can give useful tips how to get pregnant quickly using folk remedies. We list the most popular of them, the effectiveness of which has been confirmed by numerous reviews.
Having eliminated all negative factors, the only thing that remains is the most pleasant thing in life together– sex, which you also need to know how to do correctly and when it’s best to do it. Great importance have poses (photo):
After sexual intercourse, you cannot immediately get out of bed; you need to raise your legs on the wall and lie there for a while. And you shouldn’t shower for at least the next 2-3 hours.
Knowing all the pitfalls of the conception process and following the advice, you can outline your own schedule of actions and achieve success in this “difficult” task.
