To pregnancy was successful, this event should be prepared in advance. Perhaps women need to change their lifestyle, give up bad habits and eat right. You also need to visit a gynecologist and other specialists, to identify chronic diseases and their cure before pregnancy. To determine the days when fertilization is most likely applicable calendar conception.
You really want to have a baby. What you need to do first? First of all get rid of any bad habits that could harm the baby. This lack of sleep, physical and mental stress, sedentary lifestyle, eating on the run, smoking, alcohol consumption, strong tea and coffee, and so on. Can you help a calendar of conception - a question which deserves a separate study.
Calendar of conception - a very convenient schedule that maximizes pinpoint the most favorable days for the fertilization of the mature egg.
We present a special program in which a woman wishing to become pregnant, can calculate the optimal day for conception. It should immediately make a reservation. Firstly, it does not give an absolute guarantee, and secondly, it is not suitable for women who have had an irregular menstrual cycle. And, of course, can not be used for the calculation of the calendar conception of so-called safe days.
What is the calendar of conception?
In order to determine the most successful days for conception in special programs, which are presented on the sites, you must enter the following data. The first step is to specify the first day of the last menstrual period, and then the length of the menstrual cycle (e.g. 28 days). Then you need to specify for a number of menstrual cycles a woman wants to calculate the optimal days for conception (for example, three cycles). And finally, use these calculations in a given day and sexually active.
A little bit of life of ovarian physiology
The ovaries are known to play a huge role in a woman's life. It is on their proper functioning depends not only on a regular menstrual cycle, but the possibility of a woman becoming pregnant. Under the influence of hormones of the anterior pituitary gland in the ovary during the menstrual cycle produced by hormones, the number of which varies in different phases of the cycle.
The menstrual cycle is in turn divided into several phases, which are formed by the action of sex hormones, hormones, pituitary and hypothalamus. The hormones stimulate the maturation of the egg cell in the ovary, its access to the abdominal cavity and the fallopian tube, fertilization by sperm in the fallopian tube, uterus wall preparing for the introduction of the embryo, the embryo introduction, continuation of the pregnancy for 40 weeks and birth.
Each woman's ovaries contain hundreds of thousands of immature eggs, but reach full maturity only about five hundred eggs.
In the first phase (follicular) in the female gonads begin to mature follicles. Subsequently, the main among them is determined by the (dominant) follicle, which, after its dissolution should come ready to fertilize the egg. This phase is called the ovulatory menstrual cycle and it lasts an average of two days. It is this period is considered the most favorable for conception.
The best time for conception
Time release egg from the ovary (ovulation) is the best time for conception. This moment may pass unnoticed for the women, but some women experience ovulation in the form of short-term pain in the lower abdomen from the side. Confirm the time of ovulation is possible by measuring the temperature in the rectum, special test strips to determine ovulation by ultrasound. The egg retains its ability to live within a day after ovulation and during this time it can be fertilized with the greatest probability.
It is possible to conceive and if intercourse was a few days before ovulation
Ovulation - How to determine as accurately as possible?
Despite the fact that during this period in the body yet mature, ready to fertilize the egg, since sperm are living up to three or four days and it can "wait" release egg from the ovary.
The fallopian tube sperm from all sides surround the egg and penetrate its cytoplasm. It was found that the egg gets just a lot of sperm, but only the core of one of them fuses with the egg nucleus. It begins with this growth and the formation of fetal tissue, ie pregnancy.
The calendar method of determining ovulation
In an ideal menstrual cycle, the length of which is twenty-eight days, ovulation occurs on average on the fourteenth day. Normally, the time release of the egg can occur a little earlier or later. Therefore, a woman's fertile period (the time when she can get pregnant) considered three days before the expected ovulation, the day of release of the egg, and two days after that.
At irregular periods (if the difference between the duration of the cycles is from four to seven days) to determine the time of ovulation is more complicated, because it is constantly changing.
In this situation, the woman should mark the calendar length of menstrual cycles for a year and then determine the longest and shortest cycle.
Then, the following calculations:
- From the longest number of days of the menstrual cycle is subtracted the number ten;
- Because of the length of the shortest cycle is subtracted nineteen;
- These numbers indicate the days of the menstrual cycle
The days of the menstrual cycle: Four phases
Between which a woman can become pregnant.
But even with the regular menstrual cycle time of ovulation may change, and sometimes in a single cycle from the ovary at different times out two eggs. This can occur due to various reasons, such as when taking hormonal drugs or due to stress.
Sperm can remain active in the fallopian tubes of up to seven days. So if women have sex a few days before ovulation, the pregnancy may occur as soon as the egg is released from the ovary and fall into the fallopian tube.
The calendar method is not always accurate, so you can further determine whether ovulation has occurred, by the test of basal body temperature. The latter depends on the phase of the menstrual cycle.
Women should do this test in the morning, at one and the same time, immediately after waking up, getting out of bed. A thermometer inserted into the rectum to five centimeters for ten minutes. The result is then recorded or marked on the chart.
In the normal menstrual cycle for follicular (first) phase of the basal temperature is higher than 36, 8 ° C, and before ovulation, it decreases to 36 2 - 36 3 ° C. After oocyte leaves the ovary and fall into one of the fallopian tubes, the temperature reached 37, 1 - 37, 4 ° C, retained at this level throughout the second half of the cycle and decreases just before menstruation.
If a woman's body produces enough of the hormone progesterone, the basal temperature rises only up to 37 - 37, 1 ° C, lasts only three or four days. Normally, increased basal temperature is maintained from eight to fourteen days. In cases where ovulation does not occur, there is no basal temperature fluctuations, it is during the cycle remains at the same level.
To determine ovulation in this way should be for three months, and if a woman has a regular cycle, with a high probability we can determine the days on which conception is possible. It's five or seven days before the temperature jump.
How to calendar conception and use it
Optimally, if a woman starts to conception calendar year before the planned pregnancy. Here's how: take a regular calendars (better if it is a monthly desk calendar) and marked it: the date of the beginning of the menstrual cycle (first day of menstruation), the date of the end of the menstrual cycle (the first day of the next menstruation) and the date of ovulation. Below are marked all the features of the menstrual cycle. Even more convenient to keep a calendar of conception in the computer, selecting for this purpose a separate file.
Before you plan conception, a woman should make sure she had a regular menstrual cycle.
This usually takes six to ten months. This will most accurately determine when ovulation occurs - auspicious days for pregnancy. With the calendar method, you can find out if a woman has problems with reproductive health.
The cycle is considered to be a regular when the difference in six months duration of the longest and shortest cycles does not exceed four days. If this is not the case, the woman has menstrual dysfunction, and it should be examined in this regard.
After analyzing your conception calendar for a few months, you can determine exactly when ovulation and conception planning process at a time. Which starts three days before ovulation and ends two days after it (the extra day after ovulation - a correction to an error). Of course, you can only plan conception with regular menstrual cycle.
Calendar of conception with regular menstrual cycle
Get a calendar of conception in the presence of regular menstrual cycle does not make difficulties. The first, or follicular phase lasts approximately half of the menstrual cycle and ovulation typically occurs in the middle. For example, if the length of the menstrual cycle is 28 days, the output ovum on average, on the fourteenth day of the cycle.
However, ovulation can happen to the thirteenth to seventeenth day, inclusive, of the menstrual cycle.
Thus, it appears that the most favorable days of the menstrual cycle is five days (from 13 to 17 per day). You also need to take into account the life span of the sperm and the egg. The average sperm retain their activity within seven days, while the egg is viable only a day or two. From all of these reasons it follows that the best days to conceive - a menstrual period from the ninth to the eighteenth day, ie ten days (this period added another day possible activity egg). In the event of a short (21-25 days) or long (32-35 days) of the menstrual cycle favorable days for conception are also equal to the number 10, and you must count twenty days before the next menstruation. As can be seen, the method is quite simple and is suitable for all women with a regular menstrual cycle.
Calendar of conception with irregular menstrual cycle
However, not all women can boast of a regular menstrual cycle. Depending on its duration, the period of ovulation can vary. In order to calculate the favorable days for conception, it is necessary to take into account the duration of each menstrual cycle (the longest and shortest). The calculation is also simple. For this purpose from the very short menstrual cycle days 19 to be subtracted, and from the longest - 10 days. For example:
- The shortest cycle is 25 days (25 - 19 = 6)
- The longest cycle is 29 days (29 - 10 = 19)
In this case, the most successful days for conception interval menstrual cycle is from 6 to 19 day.
How to "get" the twins
Many parents would like to have twins
If you have twins: Ten Smiles
. So how do they get and whether it is possible to plan the birth of twins?
The twins can be different. Some are born as a result of fertilization of two different eggs different sperm and they have a different set of chromosomes, different looks, sometimes even a different blood group. This so-called dizygotic or dizygotic twins. The birth of twins is predetermined by inheritance (from the next of kin have been double and triple), nationality (most born twins in black women), older women (usually this happens after 35 years as the age increases hormonal stimulation of oocyte maturation, so they can mature just two).
Another type is called monozygotic twins (monozygotic). In this case, one egg is fertilized by one sperm, but the result is a two embryos. Why is that exactly is not yet established. As a result, the twins are born exactly the same: they have the same set of chromosomes, the same blood, the same appearance. The birth of monozygotic twins - the process is totally unpredictable, they are much less common than dizygotic.
Schedule having twins naturally impossible, but there are factors that increase the likelihood of their birth. Thus, it was found that the birth of dizygotic twins is often hereditary, the probability of birth of twins is higher in women with a short menstrual cycle (21 days) and in women with disorders of the uterus, which is like a split.
When the Calendar of conception is easier to implement planning to become pregnant.
