A woman is a mystery to many men. What exactly? Probably in his changeable mood, which, according to some medical workers, occurs under the influence of female sex hormones. But Eve’s daughters are so interesting that they have one feature - a monthly cycle, which allows them to become a mother. Yes, the reproductive capacity of the female sex depends on a given monthly cycle, the indicator of which is menstruation. Therefore, every self-respecting woman knows her physiological structure and she does not need a medical education for this. In preparation for conception, women stop using contraception, taking birth control pills and begin to carefully monitor their bodies and keep a conception calendar. They know that for the birth of a healthy baby and his successful conception, so-called favorable conditions are necessary for him.
Where are you, cherished days?
As is already known, fertilization depends on a mature egg.
After ovulation has occurred, the egg becomes capable of fertilization. Men and women have plenty of favorable days for creating a child. On the male side, male sperm entering the female body live up to five days. On the female side, the body allocates five days before ovulation and 15 hours after the process. This means that it is on these days that it is likely that a woman will become pregnant. The day of ovulation itself is considered the most peak, win-win. In order to get to the right day without any guesswork, a woman can create her own individual schedule by day. The main thing in planning conception is to find out the day of ovulation.
If your monthly cycle is 28 days and is divided into two phases, then ovulation occurs on the 14th day of the first phase, with periods lasting up to five days. But we all have differences that also apply to the monthly cycle. It may be shorter or longer, which is considered quite normal. In the event that its duration is less than 24 days or more than 35, difficulties in calculating ovulation and determining favorable days are quite possible. With such a cycle, in most cases, there is a failure of ovulation.
A complex approach
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 of birth control.
A few steps to creating a calendar
So, you have finally decided to become parents. This means that it’s time for the expectant mother to start drawing up a conception calendar. Based on this useful information, a woman will always be able to navigate and know when she has dangerous days, menstruation, safe days and the day of ovulation. What is needed for that?
- Take a convenient calendar in which you can make your graphic and color changes. If you keep your own personal diary, select a separate piece of paper for this purpose. If you like something larger, then a wall calendar is suitable, always in sight and close-up. There is also an electronic conception calendar. Although, handmade work is much more pleasant. Day after day, with creative inspiration, personally noting - is it comparable to automatic calculation?
- You have chosen the calendar, so the next step is to arm yourself with multi-colored markers or pencils. Whatever you like best as an artist, then take it. They are useful for highlighting colors of different days.
- Now is the time to apply the knowledge and all the information about the menstrual cycle. Such data is necessary to accurately calculate peak days.
Factors of monthly cycle failure
The following factors make it difficult to calculate dangerous days for pregnancy after menstruation:
cycle offset,
repeated ovulation (after 1-11 days),
release of the 2nd mature egg from the opposite ovary (at conception, twins are born).
Failures occur in ladies who:
- under 20 years old;
- over 45 years old;
- have sex irregularly;
- recovering after childbirth;
- stopped taking hormonal contraception;
- took emergency contraception after unprotected sexual intercourse;
- got rid of a bad habit, such as smoking;
- experienced stress, illness;
- made a difficult trip;
- went on a diet or started exercising;
- changed work schedule;
- had an abortion or had a miscarriage.
It turns out that there is no reason to blindly trust the calendar method to calculate the days after menstruation that are dangerous for pregnancy.
. After all, even a woman’s falling in love can shift ovulation, not to mention the above-mentioned factors.
Having made a brief analysis of the information presented, we can say with confidence: the last 3-5 days of the cycle are considered safe from pregnancy, provided that menstruation begins on time.
We dare to advise women to find a more reliable method of contraception, but... “There is no way to protect yourself from pregnancy if God decided to make you a mother!”
Take care of yourself and be healthy!

A woman must know which days she can conceive a child and which days she cannot. It is important to correctly calculate the dangerous days for pregnancy after menstruation. After all, unplanned pregnancy is a fairly common occurrence, despite knowledge of the physiology of your cycle.
In general, three phases of the cycle can be distinguished. In its first part, during the onset of days 5-7, blood is released in a small amount. In other words, ovulation occurs. In the middle of the cycle, the second phase of the menstrual cycle begins.
After this, the corpus luteum begins to be produced in the area of the ovary. As a result, progesterone is intensively produced. For two days, even a day after fertilization has occurred, the hormone remains at a high level. Its high rate influences to a greater extent the fact that a woman feels painful, unpleasant sensations in the mammary glands. If fertilization is not confirmed, then the hormone decreases its value. As a result, the endometrium peels off and a new menstrual cycle begins.
Often women are at a loss about which days are dangerous for pregnancy after menstruation and which are not. In particular, a week after the end of the menstrual period, ovulation cannot occur so early. Accordingly, the probability of getting pregnant is quite low.
About 10 days after the end of the critical days, “dangerous days” begin. After ovulation, or more precisely, two days after this period, “non-dangerous days” begin.
Calendar
A few years ago, to help women, the Japanese gynecologist Ogino and the Austrian gynecologist Knaus made a discovery that is still popular to this day - a natural method of contraception. Its “highlight” was that a woman can get pregnant only on favorable days for conception. According to their research, this period begins after ovulation, somewhere on the 12-15th day of the menstrual cycle. At other times there is no chance of conceiving a child. Although today the opinions of scientists differ, the main rule for a woman who dreams of the joys of motherhood still remains - this is to regularly record the menstrual cycle. If there are any, especially over the last two years, there is every reason to find out the favorable time for conceiving a child.

Contraception is an important factor in a woman's life. To prevent unwanted pregnancy, you can use a calendar: if you calculate all the days of the month into safe and dangerous, then you can with a high degree of probability prevent conception.
It is not difficult to determine the most dangerous days for conception, especially if menstruation comes regularly and there is a table that clearly indicates positive dates for pregnancy. If critical days come unsystematically or irregularly, then you should not take risks using a calendar. The best option to prevent unwanted pregnancy is to visit a doctor to select effective contraception.
To start calculation:
- Write the date of the first day of your last menstrual period.
- Please indicate the length of your menstrual cycle.
- How many days does menstruation last?
For example, the menstrual cycle is 28 days.
The duration of menstruation is 6 days. The first day of your period is November 24th. It is believed that with a 28-day cycle, ovulation occurs on the 16th day. You count from the first day of your period (16) and mark it on your calendar, it falls on (November 8). Day of maximum possibility of conception. Now, let’s find out what other favorable days there are. Also, starting the countdown, we skip 8 days and from 9 to 21 are your lucky days, that is, from November 1 to 7 and from 9 to 14. The difference in calculation can be plus or minus 2-3 days. To make your schedule more clear, mark each day with a different color. For example, the day of ovulation is blue, maybe because it is considered the color of wish fulfillment, heavenly, KD is red, that is, indicating extremeness, days on expected ovulation are yellow, reminiscent of fluffy chickens, unfavorable days are black, which means they do not represent any benefit.
Some doctors believe that if a child is conceived on “good” days, he will be born healthy and strong. Indeed, according to statistics, there is a small percentage of conceptions beyond their limit. So, it's YOUR choice!
Ovulation calculation
The monthly period is divided into three phases:
- Fertility (ovulation) lasts 2-3 days,
- complete sterility (includes the period from the last day of ovulation to the start of menstruation),
- relative sterility (probability of conception up to 15%) begins from the last day of menstruation and lasts until the onset of ovulation.
It is especially dangerous to exercise without contraception during the last week before the expected release of the egg: sperm in the uterine cavity have a long lifespan.
Methods for calculating ovulation:
1. Ultrasound (folliculometry)
. They disappear on the 11th day after menstruation.
2. Basal temperature
.
The most accurate method of determination
. After menstruation, every morning (after waking up), measure your body temperature rectally and note it in a notebook. Before the rupture of the follicle it is reduced (36.6-36.9°C), when the egg is released it sharply increases to 0.5°C (37-37.3°C). The accuracy of the temperature is impaired if the day before you had sex, took medications, or consumed alcohol.
3. Tests to determine ovulation
.
The strip appears due to the presence of the hormone “luteotropin” in the urine. Before the expected release of the egg, a test is performed daily. On the eve of release, the level of the hormone will increase sharply, which means that the follicle will rupture in the next two days. Menstrual cycle.
Ovulation 4. Subjective sensations:
Ovulation period is approaching:
the woman is in high spirits, looks great, flirts, vaginal discharge becomes more abundant, she is inclined to have sexual contact;
The follicle matures
in 1 ovary (normal), before it ruptures (for the release of a mature egg), a nagging pain is felt in it, spotting may appear, and the most favorable days for conception begin - ovulation.
Sometimes anovulatory failure occurs (1-2 times a year), when the egg does not come out.
In this case, the calendar method of calculation is ineffective, and when determining the onset of ovulation by any method, the indicators will be negative for the entire cycle.
The essence and features of protection using the safe days method
This method is based on the physiological characteristics of the female body. A representative of the fair sex of childbearing age experiences menstruation every month. This is the process of renewal of the uterine mucosa, which accompanies the release of blood from the vagina. The average duration of bleeding is 5-6 days.
However, dangerous days for pregnancy after menstruation are not so easy to calculate. This is due to the following factors:
- the possibility of menstrual irregularities associated with changes in climatic conditions, illness, stress, fatigue and other reasons:
- the lifespan of male germ cells in a woman’s body is a week or more;
- incorrect calculation of the ovulation period;
- instability of the menstrual cycle.
First of all, you need to get a special calendar. This can be a familiar paper version that allows you to mark the days of your period. A simpler and more modern solution would be to install a special mobile application that has a wide range of functions. It is necessary to keep records strictly and accurately, in order to avoid even a small error.
Based on the data obtained, it will be much easier to calculate dangerous days for pregnancy. The method includes actions such as:
- establish the average duration of menstruation for at least 6 previous cycles;
- set the time and duration of ovulation;
- subtract 5 days from the date of ovulation.
The resulting five-day period will be considered the most dangerous for pregnancy.
The second option is to calculate safe days:
- set the shortest cycle over the last 12 months;
- subtract 11 from the number of days in a given period;
- set the longest cycle;
- subtract 18 from the number of his days;
- the resulting digital range is the most favorable day for conception.
When using the method, it is necessary to realize that a woman can become pregnant on any day of the month, contrary to mathematical calculations.
Safe days for unprotected intercourse are several days (usually no more than 10 during the entire cycle) during a woman’s menstrual cycle, during which the probability of becoming pregnant is as low as possible for her. Considering that the female body is unpredictable, protection in this way is considered the most unreliable.
The essence of contraception using the safe days method is to determine the ovulatory period of a particular girl (taking into account the characteristics of her menstrual cycle) and avoid sexual intercourse during this “dangerous” period for her.
Among the main features of this method to avoid unwanted pregnancy are:
- the need to analyze the characteristic features of the menstrual cycle over several months (up to six months);
- this method of contraception is suitable only for girls with a regular menstrual cycle, provided there are no problems with hormonal levels;
- increasing risk of contracting sexually transmitted infectious diseases;
- there is a high chance of getting pregnant (despite the calculations) due to a shift in the ovulatory period within a particular cycle or an increased duration of sperm activity (depending on the man’s lifestyle).
There are several ways to calculate safe days for unprotected sexual intercourse. However, the most reliable information can only be obtained by comparing the results of several studies.
Calendar method
This method will be informative only if the girl has a regular menstrual cycle. Otherwise, despite the calculations made, the data obtained will not be able to guarantee the ability to avoid pregnancy during this period.
To use the contraceptive method in question, you must:
- Determine the longest and shortest menstrual cycle for 5 months (the beginning of the cycle is considered to be the first day of menstruation, regardless of the amount of discharge).
- A period will be considered dangerous if it begins on a day calculated according to the principle: the number of days in a cycle is 17.
- Unprotected sexual intercourse can be practiced during the period, the beginning of which is recommended to be determined using the following calculations: the number of days in the cycle is 11.
The calendar method for calculating safe days for unprotected intercourse is not suitable for women whose menstrual cycle is most often shorter in duration than the generally accepted norm (28 days). In all other cases, according to statistics from gynecologists, the probability of becoming pregnant without protection during the period calculated in this way is 30–40 to 100.
Cervical mucus is vaginal discharge produced during the functioning of the cervix under the influence of female sex hormones. By carefully analyzing its consistency, as well as the quantity on different days of the cycle, a woman can assume that the ovulatory period is approaching and exclude unprotected sexual intercourse during this period.
A few days after the start of your period, cervical mucus will be thick, sticky, and cloudy (usually white or beige). In this form, it acts as a kind of barrier for sperm trying to penetrate the uterus.
As the day of ovulation approaches, the discharge becomes more liquid and transparent, which increases the risk of fertilization of the egg, subject to the “increased vitality” of the male seed. On the very day when the egg leaves the follicle, cervical fluid is released in a particularly large volume, and it has neither odor nor color.
The cervical mucus method, used to determine safe days of the cycle, is ineffective for a person far from medicine. Changes in the consistency and color of vaginal discharge may indicate not only a change in the phases of the menstrual cycle, but also problems in women's health.
Safe days for unprotected intercourse can also be determined by measuring basal temperature daily. Provided that the body functions normally in the first phase of the menstrual cycle, the basal temperature does not rise above 37 degrees Celsius due to the presence of a high concentration of estrogen (female sex hormone).
During the ovulatory period, a corpus luteum forms at the site of release of the egg, provoking the release of progesterone into the body, which contributes to a sharp increase in temperature (usually up to 37.4 degrees Celsius). An elevated basal temperature can persist for several days, after which it gradually begins to normalize, slowly decreasing to 36.6.
If, after measuring the basal temperature for 3-4 months, the girl does not detect its increase in the middle of the cycles, it is necessary to contact a gynecologist as soon as possible to undergo an examination to identify ovarian dysfunction (if a temperature jump does not occur, then the cycle is considered anovulatory, which indicates about a woman's possible infertility).
Using the method of measuring basal temperature to determine safe days of the cycle, the girl should adhere to the basic recommendations of gynecologists.
They are:
- conduct a similar study for at least 4-5 months in a row;
- record the result every day at the same time (doctors advise taking measurements in the morning, without getting out of bed after waking up);
- use the same thermometer;
- for the convenience of estimating the rate of increase in basal temperature, draw up a graph using a curve;
- measure temperature through the anus.
The symptothermal method involves assessing changes in the girl’s general condition during various phases of the menstrual cycle.
Considering that the symptoms of approaching ovulation are a subjective indicator and also vary from cycle to cycle depending on secondary circumstances, this method of identifying safe days for unprotected sex is considered one of the most uninformative.
| Symptom of approaching ovulation | a brief description of |
| A sharp increase in sexual desire | It occurs on a subconscious level under the influence of hormones, whose functioning is aimed at ensuring that the released egg is fertilized in this particular menstrual cycle. |
| Enlargement of the mammary glands, as well as increased breast sensitivity | Such changes in the female body are associated with its nature and inherent preparation for a potential pregnancy. |
| “Dull” nagging pain in the lower abdomen | The discomfort is usually caused by the follicle rupturing and the egg being released into the fallopian tube. In some cases, ovulation may be accompanied by light bleeding that persists for 2-3 days. |
Ovulation test
Safe days for unprotected intercourse can most reliably be determined using special ovulation tests, which are freely available at pharmacies. Usually, several test strips are sold in the package, which are similar in appearance to tests for determining pregnancy.
To satisfy the requirements of the vast majority of consumers, they offer digital, electronic and paper tests, which differ from each other in the way the study is conducted, as well as in the speed and accuracy of giving results.
To understand what phase of the menstrual cycle a girl is currently in, you need to:
- Conditionally divide the average number of days in a cycle by 2.
- Subtract 3 from the result obtained and, starting from this moment, conduct the test every day for 5-7 days (to do this, place the test strip in a container with urine and hold it for 3-5 seconds).
- The ovulatory period can be recognized by the presence of two bright stripes in the control zone of the test.
When planning your sex life based on the results obtained, a girl should remember that the average lifespan of sperm is 5 days. Therefore, by practicing unprotected sex before ovulation, a girl risks not only contracting infectious diseases, but also becoming pregnant.
