Each month women are prettier one or two days than usual, and this has been proven to coincide with the peak of their fertility.
Fortunately, other methods are also available if someone wants to know if they are in the fertile phase of their cycle. Now we take these methods in a row including fertile saliva ferning patterns but let’s clarify a few things first.
6 fertile days per cycle
The probability of becoming pregnant is highest in the five days before ovulation and on the day of ovulation. In 1995, 221 women who wanted a child were asked to record the days they had intercourse without contraception.
The exact day of ovulation was determined from urine samples based on the hormones estrogen and progesterone. A total of 629 cycles were studied, during which 129 babies were born out of 192 pregnancies.
The pregnancies with only one occasion of sexual intercourse were examined separately. These all occurred five days before ovulation or on the day of ovulation.
Based on all cycles, that includes when couples have sex multiple times, they also estimated the chances of conceiving on a given day.
The study concluded that sperm survive in the female body for up to five days after intercourse. After ovulation, the ovum can be fertilized for up to 1 day. Thus, these six days are the fertile phase of the cycle.
The most fertile day
The fertility peak is two days before ovulation.
We know this from a 2007 study in which 728 pairs were examined based on baseline body temperature. They were similarly asked to record the days of unprotected intercourse. The body temperature test does not show precisely which day the ovulation was, because it must be estimated retrospectively. However, the six-day fertility window can also be seen here.
Examining the 5390 cycles and 434 pregnancies, the study came to the conclusion that if we know the day of ovulation, it is worth scheduling the being together two days in advance. This is the best chance of conception.
If we understand what hormonal processes are going on in our body and pay attention to the signs that accompany them, we can estimate the day of ovulation.
As a first step, estrogen levels in the body begin to rise, and in parallel, the salinity of body fluids increases. Then you should pay attention to the following:
- cervical softness, position,
- consistency of the cervix,
- increase in mucus and saliva electrolyte levels,
- crystallization of salts in mucus and saliva samples.
These methods including the fertile saliva fern pattern can indicate 3-4 days earlier that our body has begun to prepare for ovulation. In addition, there are less measurable signs such as a more attractive appearance, higher sexual desire, and e.g. greater sensitivity to odors.
As a second step, the pituitary gland releases large amounts of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) into the bloodstream. As a result, ovulation may occur 1 to 1.5 days later. At the same time, baseline body temperature, heart rate, and respiration increase, and LH can be detected in the urine. So these signals predict ovulation approx. 1 day in advance.
As a third step, the enlarged dominant follicle shrinks in size and develops a corpus luteum. Estrogen production is also reduced and progesterone production is started, which aids in implantation. The size change of the follicle is clearly visible by ultrasound examination. Therefore, clinics examine the dominant follicle with ultrasound on a daily basis, it is clear from this whether ovulation has occurred or missed.
Is there a cycle without ovulation?
Sometimes the first two steps take place, but ovulation does not occur. The frequency of ovulation decreases with age.
However, keep in mind that two ovulations are possible in one cycle. This occurs in 1-2% of cases. However, both eggs are not always fertilized. Just think of how rarely do we meet fratenal twins.
To conceive, on the other hand, you need to ovulate, that is, you need a mature egg ready to be fertilized. Since the cell released from the ovary lives for about 1 day, while the sperm can wait for 3-5 days, good timing is needed for success.
Home ovulation tests
With regular cycles, body temperature or urine tests can work great. These products measure changes in basal body temperature and / or urinary LH by approx. 1 day before ovulation. The data is collected by a mobile application that comes with the product for 3 months. It then calculates and signals when the fertile phase begins. This, in turn, means that the most fertile day is not indicated by actual hormone changes, but by data measured in the past.
With irregular cycles, we can only rely on an increase in estrogen levels a few days before ovulation. Unfortunately, approx. 1/3 of women has irregular cycles that depend on age, health, lifestyle and weight.
Nonetheless, more and more people are using methods to measure the rise in estrogen levels. Of these, there is already a mobile application for the ovulation saliva test and for the changes in electrolyte levels.
Using an ovulation microscope, fern-like patterns, crystals in saliva can be observed. Many women can determine fertile days based on this. Of the applications, however, only Babyndex is able to recognize fertile saliva fern patterns. At the current stage of development, it shows the probability of the occurrence of crystals, but it will soon indicate the peak of fertility in a personalized way. According to a study by Harvard Medical School, the ovulation saliva test can predict ovulation with 99% accuracy by image recognition of crystals. The Babyndex application aims to help more and more women in identifying the most fertile saliva fern pattern.
Measuring electrolyte levels requires an order more expensive devices. The first mobile applications for these enter the markets now.
So when can I get pregnant?
When the body begins to prepare for ovulation, it is possible to get pregnant. The peak of fertility is two days before ovulation, but the exact day cannot be known in advance. In fact, it may be omitted.
Changes in body fluids predict ovulation first e.g. during the fertile phase saliva ferning patterns predict it. The Babyndex application recognizes these patterns as not only women are prettier at the peak of fertility, but also their crystals.
