Normally, the ovum leaves 13-15 days before the start of the period. In medicine, there are concepts of early and late ovulation. However, this definition is not general, but is suitable for describing a specific case.
Early ovulation is the maturation and release of an ovum earlier than usual. For example, for a 28-day cycle, ovulation on day 9-11 is considered early. This is not an abnormality.
This situation may arise for the following reasons:
- Excessive exercise.
- Climate change.
- Nervous overvoltage, prolonged stress.
- Alcohol consumption.
- Taking some medicines.
- Hormonal imbalance.
- Artificial termination of pregnancy.
- Inflammatory diseases.
- Sleep disturbance.
- Active sex life.
In addition, fluctuations can occur during the year, for example, in summer it will be earlier because of the hot weather. Early maturation of the egg also occurs after delivery.
Late ovulation can be called when the egg is released later than usual. For example, if you have a 30-day cycle, it is for 20-21 days. This often makes it impossible to get pregnant because of incorrect timing, as partners try to have sex in the middle of the cycle.
Important: Sometimes this situation affects the wrong timing of pregnancy.
The reasons for late ovulation:
- Excessive physical and mental stress.
- Use of medicines for emergency contraception.
- Infectious diseases.
- Hormonal failures.
- Recent birth or miscarriage, abortion.
Early and late ovulation are relative concepts and are not considered deviations.
How many days in different cycles
The ovulatory period is different for everyone at different times, depending on the cycle. There is still no consensus on how long it lasts. Some physicians believe that only 24 hours, others lean towards the figure of 48 hours. It is generally accepted to count the duration – 24-36 hours.
The menstrual cycle consists of follicular, ovulatory and luteal phases. The follicular period continues from the first to the beginning of the cycle to the beginning of ovulation, the ovulatory period is the process of ovulation of the ovule, followed by the luteal period, which lasts until the onset of menstruation.
After the monthly ovaries, there are follicles no larger than 10 mm in size. Only one begins to mature and increases to 20-25 mm. This is the dominant follicle. When exposed to hormones – hCG, and lutein – the follicle burst, the egg is released into the abdominal cavity. It then enters the uterus tube. After fertilization, the cell moves along the tube to the uterus, where it is fixed. If fertilization has not occurred, the ovum dies.
Taking into account the life expectancy of sperm cells in the woman’s body (5-7 days), the possibility of pregnancy during planning arises a couple of days before the release and is maintained 24-36 hours after.
Duration of ovulation in:
- 28 day cycle – from 14 to 15 days.
- 29 days – from 15 to 16 days.
- 30 days – from 16 to 17 days.
The main signs of the beginning the menstruation
When the egg comes out, there is a surge of hormones, which can be used to determine that it has happened.
The following symptoms are observed in the woman:
- Increased secretions. They become more dense and mucous membranes.
- Minor lower abdominal pain that occurs after ovulation.
- General malaise: dizziness, weakness.
Important: If you feel much worse, the pain increases, you should see a doctor. This may indicate inflammatory or tumour-related conditions.
The exact onset of ovulation can be determined by measuring the basal temperature. From the moment of the end of the month and for 7-9 days the temperature will be within the range of 37 degrees.
Just before the egg leaves the egg, there is a sharp rise in temperature by 0.5 degrees. If the temperature has not changed, the cycle is considered an anovulatory.
It is easy to determine the beginning of ovulation using special tests. They are based on increasing the LH (luteinizing hormone) in the urine. Its concentration increases 24 hours before ovulation, which is confirmed by the appearance of two strips. If one line is pale, the egg has not yet been released, but will be released in the next few hours.
Important: The tests are highly accurate and avoid the possibility of error.
The most accurate control method is ultrasound, which shows the maturation and rupture of the follicle.
Ovulation is a natural process in which the egg is released, ready for fertilization. This process can be influenced by various factors, from hormonal failures to banal weather changes or fatigue. It is normal for a woman to have one or two anovulatory cycles during the year. Their number increases with age.
Duration of the process, time of occurrence – these are individual features. Small fluctuations in the timing are considered a variant of the norm and do not require treatment.
How many days does ovulation last in women?
Ovulation lasts about 12 to 24 hours. In addition, some women feel the egg cell output and can say not only when it happened, but even in which ovary developed a dominant follicle, from which the female sex cell was subsequently released.
The most characteristic signs of this process include severe abdominal pain, excessive discharge from the vagina and increased sexual need.
It is difficult to say exactly how long the ovulation will last, because it is a purely individual process, depending on a huge number of factors, ranging from the reproductive health of the woman and ending with the physiological characteristics of her body.
From the moment the egg is released until its death, which happens 12-24 hours after ovulation, the chances of successful conception are maximal. How many days after ovulation you can get pregnant – no more than 1 day. In turn, sperm cells are able to maintain their activity much more – up to 5 days. Therefore, even if the sexual intercourse takes place 2-3 days before ovulation, the probability of pregnancy will be almost as high as intimate contact on the day of egg production from the follicle.
How to calculate the day of ovulation and its duration?
There are several ways in which you can determine the day of ovulation. The easiest way to do this is with a regular menstrual cycle. For example, with a standard 28-day cycle, the oocyte output is in the middle of the cycle, i.e. on 14-15 days. It is also worth knowing that there is one feature that determines the duration of each phase.
The first follicular phase in all women has different duration, because the maturation of female germline cells – a process that is purely individual. The duration of the yellow body phase is always the same – 14 days. It is after this time that the body finally understands that conception has not taken place and that it is worth preparing for a new menstrual cycle.
It follows that in order to get the date of ovulation, it is necessary to deduct 14 days from the total number of days in the menstrual cycle. For example, with a duration of 32 days of MC, the maturation of the female sex cell will take place on 32-14=18 days.
If the cycle is unstable, it will be more difficult to calculate the egg production day. In order to obtain more reliable data, it is desirable to monitor the duration of the MC during the last 6 cycles. Thanks to this, it will be possible to use the following scheme: we take away 18 from the least prolonged IC, which will be the first fertile day, and 11 from the longest one, which will be the last fertile day.
Let’s consider the offered variant of calculation of a fertile window on an example: the shortest MC for last half-year – 25 days, we take away 18 and we receive 5, and the longest – 35 days. We take away 11 and get 24. On the basis of the received results we draw a conclusion that the most suitable time for conception are days from 5 to 24 number of MC.
In addition to this calculation method, there are other ways to determine the onset of ovulation:
- Basal temperature measurement. By the approaching date of egg production from the follicle, the egg will increase.
- Use of special tests.
- Ultrasound diagnostics.
By the nature of cervical mucus – it becomes less viscous, making it easier for sperm to reach the “target”.
Getting an analysis of the luteinizing hormone, which starts to grow before ovulation. But this option does not always show a reliable result, because the growth of LH may be due to other changes in the body.
How long does ovulation last
Every month, the woman ovulates herself – the moment when a mature egg comes out into the abdomen waiting for a sperm. How long does the ovulation last? Many people recommend this calculation: the middle of the cycle, about two weeks before the start of menstruation. But there is a disadvantage. This is a very general calculation, because each organism is different. Some people ovulate in 16 days and some in 10 days. There is a difference! Moreover, a woman may have an irregular cycle, which, in turn, provides additional difficulties.
If your cycle is regular, you can use the basal temperature measurement method or ovulation tests (sold in pharmacies).
There are two other concepts. Ovulation can be early and late. Early ovulation is called ovulation if it occurs earlier than you normally do. For example, ovulation that occurred on day 11 with a 28-day cycle can be called early.
The reasons for early ovulation can be too frequent sexual intercourse, intensive training at the gym, a debilitating diet, weight lifting, illness or hormonal disturbances. Late, on the contrary, will be 18-20 days later. But it is possible to call ovulation early or late only individually.
How long does it take to ovulate? A few minutes. This process can be compared to a small explosion in the ovary. It can happen at any moment during the entire ovulatory period. This releases the ripe ovum. As soon as the egg is completely free, the ovulation has occurred. In other words, it does not last, but all these processes are called the ovulatory period.
Now the ovum enters the uterus tube and waits for a sperm within 24 hours. If the sperm penetrates and fertilizes the egg during this time period, we can say that conception has occurred. Therefore, it would be wrong to say exactly how many days the ovulation lasts. It is only possible to determine the time of viability of the egg after ovulation.
The follicle is torn by the luteinizing hormone, the level of which rises many times before ovulation. Thus, blood or urine analysis can determine the approaching ovulation. This is the phenomenon on which pharmacy tests are based.
Approximately 16 to 32 hours. Many women feel the ovulation and can tell not only on which day the ovulation began, but even in which ovary it happened. The most characteristic features are: sharp pain in the abdomen, increased secretions and changes in color, increased libido.
After ovulation, the ovum still exists for a few hours – from 12 to 48. How many hours of ovulation do you have? During this entire period, the fertility rate is fully maintained.
Most medical sources call it the daily ability of the ovum. Sperm cells are much stronger, they can wait up to a week for their moment. Therefore, if we talk about the most likely period for conception, we can name a few days before ovulation and a little time later.
Determination of ovulation is very important for couples planning a child. This process is also important for the woman herself, because it is the most important indicator of her fertility.
Ovulation begins immediately with puberty and continues until the woman has post-menopause. When a woman gets pregnant, the maturation of the eggs stops, resuming for one year after delivery.
Regular ovulation indicates that the woman’s gynecological health is normal. It is also normal if the ovum has not matured within one year.
The older the woman gets, the longer these periods are. Sometimes the egg is matured twice in the same menstrual cycle.
In general, everything depends on many factors, including the health of the woman, emotional state, addictions, violation of the hormonal background, taking medicines, work in harmful production, etc., as a rule, on average, ovulation falls in the middle of the cycle – about 12-15 days from the countdown to the first day of the last menstruation.
Knowing the days on which this period falls, it is possible to calculate the chances of conception as accurately as possible.
A woman’s cycle is constantly changing, for example, after the birth of a child, abortion, and during the subject period.
If ovulation does not occur for several consecutive monthly cycles, we can talk about reproductive health problems of the woman. And here, only specialists can help to get pregnant.
When ovulating the female body is experiencing a very rapid hormonal surge. It is it that affects the basal temperature and allows you to easily determine the day of ovulation on schedule.
While ovulation lasts just before it, the temperature drops slightly (the medical term is ovulation trap), and the day after ovulation the temperature rises again, compared to the average temperatures before the maturation of the egg.
Therefore, a woman planning a pregnancy should take into account her body’s peculiarities and determine the ovulation days according to the average temperature schedule, without relying on general calculations. You can undergo a special study on ultrasound – folliculometry. This will make it much easier to determine ovulation.
- The follicular (menstrual) phase begins on the 1st day of your period. At this time, follicles begin to develop in the ovaries.
- From day 7 until the middle of the whole cycle the ovulatory phase occurs. During this period, a bubble – a special follicle – comes out of the grapheme. It is in this phase that the ovule matures.
- On the 14th day of the cycle there is ovulation. The Graaff’s bubble explodes, and a ripe egg is pushed out of it, capable of becoming the beginning of a new life. The woman feels a little pain. After that, the egg goes into the uterus, penetrating it through the fallopian tube, and lives there for another 1-2 days. Answering the question of how long the ovulation period lasts, the women answer that they got pregnant within five days of receiving positive results for the luteinizing hormone (LH).
- On the 15th day, the yellow body phase takes place – with the end of ovulation and before a new menstruation. The walls of the bursting grapefruit follicle are collected, like the petals in a bud, accumulating fats and lutein pigment, giving them a yellow color. Now this follicle is called a yellow body.
