Fertile days calendar. How to calculate fertile and infertile days?

Knowing the fertile days calendar should be a basic knowledge of every menstruating woman. It is the source of knowledge about fertile and infertile days, which is crucial in the case of natural methods of contraception. Calculating the fertile and infertile days tells us when unprotected intercourse can result in pregnancy, and what days it is better to avoid it if we are not ready to become parents. What does the menstrual calendar look like? The fertile days calculator will help us determine the fertile days and the day of ovulation.

What is the menstrual cycle?

Aby calculate fertile days, you should know, what the menstrual cycle looks like. The menstrual cycle is a symptom of changes that take place in the woman’s body. These changes take place thanks to and with the participation of hormones and show the successive stages in which the woman’s body prepares for admission and implantation of a fertilized cell. If you keep a close eye on your body, you can calculate when you will have your fertile days, which are the days when you are most likely to become pregnant. A convenient method of supporting the calculations is also the fertile days calculator.

What is ovulation?

Ovulation in women occurs in the middle of the cycle. If we assume that the cycle lasts 28 days, then ovulation (or ovulation) will occur on the 14th day of the cycle. This is the easiest time to get pregnant. This is when the body releases an egg which fertilizes when it comes into contact with the sperm. This period is called peak of the menstrual cycle. However, this does not mean that only then we have a chance of getting pregnant.

During the ovulatory period, i.e. +/- 2 days from ovulation, we are dealing with the so-called fertile days. However, their calculation is not so simple and depends on many factors, such as the length of the menstrual cycle, its regularity, and the woman’s age.

The easiest way to find out your ovulation date and fertile days is to use our fertile and infertile days calculator

Fertile days calculator allows you to quickly (with regular cycles) determine when to expect ovulation and when risk of becoming pregnant is the smallest. The information he needs to calculate ovulation and fertile days is the first day of the last period and the average length of the cycle.

Fertile days calendar

The fertile days calendar is used to identify the different phases of a woman’s cycle and is also called a marriage calendar. However, it must be remembered that there are sometimes disturbing situations woman’s menstrual cycle. These are most often infectious diseases, weakened immunity or prolonged stress. Then, it is difficult to accurately determine the fertile days with the help of a calendar. To counteract the decline in immunity, try Bio Maca 500 mg, a dietary supplement that strengthens the immune system.

In order to monitor your cycle on a regular basis and determine your fertile and infertile days yourself, you need to know phases of the menstrual cycle. There are three phases to them.

1. Relative infertility phase. In the fertile calendar, the phase of relative infertility is considered to be the time before ovulation. It begins on the first day of the cycle, which is the day that menstrual bleeding occurs. It is also at this time that the egg matures and prepares to enter the second phase. Since she is still immature and still in the Graaf vesicle, theoretically, fertilization should not have occurred during this time. Sometimes, however, if a woman has a short menstrual cycle and sperm is still in her genital tract, the fertile days after her period may come sooner and fertilization may occur. So if we use the fertile days calendar as a method of contraception, it is worth keeping this in mind. This phase is characterized by sticky mucus, of which there is relatively little in the genital tract. This is why, especially during intercourse, we may feel vaginal dryness.
2. Fetal phase. In the fertile calendar, it is considered the time when ovulation occurs, that is, the release of an egg into the fallopian tube. It is assumed that it begins 3 days before ovulation and lasts 2 days after its completion. It is during this time that there is the best chance of fertilization of an egg released into the fallopian tubes. If an egg is not fertilized within 24 hours of being released, it begins to die. However, if a woman has long menstrual cycles, the fertile phase may lengthen. It is worth taking this into account when applying for a child. In the fertile phase of the menstrual cycle the mucus is transparent and malleableresembles raw egg white. The amount of mucus secreted by a woman’s genital tract depends, among other things, on the woman’s hormonal balance. It is assumed that the more mucus, the greater the chance of fertilization.
3. Absolute infertility phase. In the fertile days calendar, this is theoretically the period in which the egg cell has died preventing fertilization. For couples who are trying to conceive, it may be a recovery phase before the next fertile phase, and for those who are not planning a baby – a time when they can safely have sex without the use of additional contraception. However, it must be borne in mind that when sexual intercourse occurs at the end of the absolute infertility phase, the sperm that enter the woman’s genital tract may survive and wait until the next phase. There is very little mucus in this phase of the cycle, and if it does appear, it may be creamy.

One way to predict the dates of each cycle phase is to use the fertile days calculator. It makes it easier to determine the probable day of the next ovulation, fertile and infertile days, but it has its limitations. Therefore, in order to prepare an individual calendar of fertile days it is also worth monitoring the course of individual phases of the menstrual cycle on your own. Methods for calculating fertile days, including recording body temperature, as well as observation of mucus and symptoms, are also helpful.

To measure body temperature and determine the time of ovulation, you will need the Medel Fertyl Ovulation Thermometer, which you can buy at an affordable price at medonetmarket.pl.

Unclear issues are best discussed with your doctor. If you have questions, speak to an online gynecologist to learn more about the fertile days calendar and pregnancy planning.

Methods for calculating fertile days

If we want to be aware of our cycle phase and know when we are dealing with fertile and infertile days, it is worth calculating these days yourself. Although the fertile days calculator is useful for regular cycles, it is important to supplement the data obtained with it with self-observation of the organism. There are several methods of calculating your fertile days that can help you with this. These are:

1. The thermal method, also known as the Holt method. Calculating your fertile days using this method is based on taking your body temperature every day. For the effectiveness of this method, the most important thing is to measure your body temperature at the same time each day, right after you wake up, preferably while still in bed. The measurement result should be written down in the notebook and compared to the measurements on the following days. Why is it so important? Because body temperature in the fertile days is on average 0,2 degrees C higher than on other days. The lowest temperature should be recorded in the period from menstruation to the beginning of ovulation. Then, from ovulation to the beginning of menstruation, the temperature will rise. About the fertile days will be indicated by the most sharp rise in temperature. However, it is worth remembering that this method does not work in the event of the development of an infection, when the increased temperature is caused by a virus or bacteria. You can measure your exact body temperature with the Tm-F03BB electronic non-contact thermometer.
2. The Billings method, which is based on the observation of mucus during different phases of the cycle. The mucus produced in a woman’s genital tract varies in consistency and quantity at different stages of the cycle. Just after your period, it is low, and if it does, it is sticky. When more of it appears, it is dragging and transparent, we are talking about the fertile days. It usually appears as early as 6 days before ovulation. In the next phase of the cycle, it becomes less and thicker again, making it harder for sperm cells to get into the egg for fertilization. How to check what mucus we have? It is enough to take a clean handkerchief and stand in your legs and use your finger to collect it from the vaginal opening and place it on the handkerchief. In this way, we use our fingers to judge its consistency, and thanks to the handkerchief – its color.
3. Symptothermal methodwhich combines the thermal method and the Billings method. It uses the same body temperature measurements as in the thermal method and observation of vaginal mucus as in the Billings method. In addition, the symptothermal method also takes into account other accompanying symptoms, such as abdominal pain or deterioration of well-being. Very often, malaise combined with pain in the lower abdomen indicates the moment when ovulation has started.

At the stage of pregnancy planning, it is worth focusing not only on the fertile days calendar, but also on the safety of the mother and child. For this, it is wise to have blood and urine tests performed for women planning a pregnancy. They will allow you to make sure that your current health condition is favorable for your pregnancy.

In addition to the increase in body temperature and changes in the consistency of the cervical mucusYou can recognize your fertile days by the appearance of other symptoms. One of them is abdominal pain, which most often occurs just before ovulation. It may appear once or cyclically, every month.

Hormonal changes related to the upcoming ovulation increase libido. During ovulation and fertile days, a woman feels greater sex drive. Interestingly, research has shown that its appearance also changes to a better one. The skin condition improves, the breasts become fuller (and therefore more tender) and the lips more prominent.

Another method of determining your fertile days is monitoring the cycle at the gynecologist. The doctor performs an ultrasound examination of the reproductive organs, during which he observes the expansion of the Graaf follicle and the moment when it should burst.

Remember that calculating the fertile days and the infertile days is a very individual matter. Calculating them requires not only a perfect knowledge of your body, but also regularity and accuracy. In addition, the correctness of measurements may be disturbed by various factors, such as a stressful period in life, illness or feeling too much pressure while waiting for a child. If you want to protect yourself against pregnancy, hormonal contraception or an intrauterine device will be a better solution. A gynecologist will help you choose the best method of contraception during a follow-up visit.
