Calculation of fertility to get pregnant

 how to understand which are the most fertile days of the month to increase the chances of getting pregnant

Calculation of fertility

How to calculate the fertile period to get pregnant ? Let’s find out all the ways to know which are the fertile days of the month, to maximize the chances of  conception .

Fertile days calculation

The calculation of the fertile period must first be done by keeping your menstrual cycle under control for a few months, in this way we will know how long the cycle lasts, when the menstruation arrives and therefore it will be easier to calculate the fertility period.

In a monthly menstrual cycle that lasts, on average, 28 days, the calculation of the fertile period will be made starting from the last day of menstruation and going on for 14 days: the time window of fertility is that of about 4 days, straddling the ovulation.

Calculation of the fertile period to get pregnant

The egg is produced by the ovary and travels along the fallopian tubes to the uterus: if it is not fertilized it will flake off and will then be expelled with menstruation. Its life cycle is about 24 hours, during this time it can be fertilized by a sperm during its journey. The spermatozoa can survive up to 72 hours and even more: this means that the window of the fertile period is about 4 days, i.e. those immediately preceding and immediately following ovulation.

Calculation of ovulation of the fertile period

It is therefore possible to calculate the days of ovulation with a certain forecast using different means:

  • ovulation strips : these are available in pharmacies and measure the concentration in the urine of a hormone, LH LH, the luteinizing hormone, which increases when you are about to ovulate. The strips are colored at the peak of the hormone in the urine and indicate, therefore, which are the right days to concentrate sexual intercourse aimed at conception;
  • basal temperature : the temperature rises by about half a degree on the day of ovulation compared to the rest of the month. To use this method it is important to measure your temperature for three months to understand what your basal reference temperature is;
  • cervical mucus : vaginal mucus changes in consistency, color and quantity at the fertile days. It becomes similar to egg white, stringy, more watery, transparent white in color and is much more abundant. The combined observation of cervical mucus and basal temperature allows you to have a fairly precise idea of ​​what the day of ovulation is.

Calculation of fertile days after your period

As mentioned, generally, in a cycle lasting 28 days , ovulation will occur around the middle of the month, therefore around the 14th day. But a lot depends on the average duration of the cycle: not all women have a cycle that lasts 28 days, some 26 days, others even shorter and the date of ovulation depends on this figure.

Fertile week calculation

We can try to calculate the most fertile days of the month using the so-called Ogino-Knaus method . In practice, it consists in taking note of the average duration of each menstrual cycle for a few months and then being able to know, with a certain probability, which is the most fertile week .

How to calculate the weeks? Let’s say that our monthly cycle, that is the days that pass between one menstruation and the next, lasts 28 days (the average duration of most women of childbearing age) and that menstruation arrived on the 1st of the month: the most fertile days will be those between the 11th and 17th days after your period.

This is because, according to this method of calculation fertile week type probabilistic , ovulation will occur around the 14th day, in correspondence with an increase in the levels of LH and estrogen hormones . The egg, as we have said, survives for 24 hours but the spermatozoa can remain viable even for 4 days, so to increase the chances of conception we must consider fertile both the days before ovulation and the following ones.

Of course, if the cycle lasts less than 28 days or longer, the stone will shift and ovulation will probably occur before the 14th day or later.

Fertile days with an irregular cycle

Of course, all the probabilistic ovulation calculations we can do to get pregnant risk not being effective if you have an irregular cycle. It is difficult to establish with a calendar measurement which are the fertile days if the duration of the cycle changes continuously. In these cases we can rely on sticks or computers to calculate ovulation, which measure the increase in the levels of the hormones estrogen and LH and therefore are quite reliable, or on the interpretation of the signals that our body sends us when we are ovulating.

Symptoms of the fertile period

A lot of changes take place in our body in preparation for ovulation and we can become quite adept at reading these symptoms and knowing when we are ovulating.

  • Cervical mucus: far from the fertile days it may even be absent or in any case present in small quantities, in a more lumpy consistency. When we are about to ovulate, however, it becomes more stringy, abundant, liquid because it serves not only to create a more favorable vaginal environment for the sperm but also for the possible implantation of the embryo.
  • Basal temperature: our body temperature rises by 02, -0.5 degrees at ovulation, so if we measure the temperature for a few months in order to know what our standard temperature is, we can understand what the fertile period is, especially if we combine the analysis of cervical mucus with this measurement.
  • Tense and sore breasts is another typical symptom of oncoming ovulation
  • Pain and cramps in the lower abdomen : those who suffer from painful ovulation may feel the arrival of ovulation because they suffer from pain in the abdomen or even in the ovaries.

Calculation of infertile days

If you want to avoid unwanted pregnancy, you can use natural contraceptive methods to try to calculate the infertile period . Obviously it’s not the best way to try to avoid pregnancy: condoms and hormonal contraceptives are the most effective ways to avoid getting pregnant if you don’t want to. The non-fertile days of the cycle are, generally, those immediately before and immediately after menstruation, but it must be taken into account that, especially after the age of 35, you can have a double ovulation, the cycle can begin to be irregular and therefore it is more difficult to calculate infertile days with some certainty.

Ovulation and nesting

In the event of fertilization of the egg by the sperm, a zygote is formed which travels in the fallopian tube, multiplying its cells and heading towards the uterus, where it will implant. This nesting process, also called implantation, can take place within five to eight days, at the latest within 12 days after fertilization. The implantation of the embryo can be accompanied by slight losses, precisely called implantation losses that some may even mistake for an abnormal menstruation.

Calculation of ovulation online

On the Net we find several resources to be able to monitor ovulation and the monthly cycle so as to know which are the fertile days. Generally it is sufficient to enter the average duration of the cycle, the day of the last menstruation to obtain a graph that highlights the most fertile period of the month.

Clearblue Ovulation Calculator

Clearblue has studied different types of ovulation sticks and tests , from those that identify the two days of maximum fertility to the more advanced ones that are able to identify the 4 days of greatest fertility each month.

Clearblue Digital Ovulation Test with Dual Hormone Indicator

It is the advanced ovulation test, capable of identifying an average of 4 fertile days for each cycle. The device detects the two main hormones associated with fertility (luteinizing hormone LH and estrogen) and identifies days with high and maximum fertility. The digital display clearly shows a smiling Clearblue face to indicate the best days for conception.

PROS : Most Amazon customer reviews are positive. The test is easy to use and would be a great help in getting pregnant.

CONS : someone complains of a malfunction linked to the emoticon led.
