Calculate ovulation and plan pregnancy

You want to have a child and get pregnant as soon as possible. Then it can be very useful if you can calculate your ovulation. Because the day of your ovulation is the time of the highest fertility and offers you the best chance of a quick pregnancy. But even up to five days before your ovulation you have the possibility to get pregnant through sexual intercourse. This is due to the long survival time of the sperm, which can wait up to five days in the fallopian tubes for your egg. So if you can now calculate your ovulation, this will help you a lot in getting pregnant with the right timing.

For a particularly simple, fast and accurate calculation, we have developed our ovulation calculators Lady-Comp or Pearly. They save you time-consuming measuring, logging and evaluating and help you to get pregnant with the right timing.

Stress-free waiting for the positive test

If you've been trying to get pregnant for a while, you may be worried that something is wrong with you. In the vast majority of cases, there are no physical causes for not getting pregnant. Even in healthy women between the ages of 20 and 30, the probability of pregnancy per menstrual cycle is only about 30% - even with the best timing!

If you are older than 30, you may also not ovulate every cycle. This is completely normal and is related to the decreasing hormone production. However, this does not mean that you can no longer get pregnant. It may just take a few cycles longer.

In men, by the way, fertility gradually decreases from around the age of 40. At this time, sperm production begins to decrease and the ability of the remaining sperm to fertilize also slowly decreases.

A waiting period of 6-12 months is therefore still considered completely normal from a medical point of view. Only if pregnancy has not occurred after a year without contraception and with sexual intercourse on the fertile days, do doctors recommend having possible causes medically clarified.

Ovulation: Why? When? How often?

Ovulation is the prerequisite for fertilization of the egg by a sperm cell and thus the basis for the development of new life. Ovulation is at the end of your fertile phase, when the cervix is slightly open and the cervical mucus is permeable to sperm. In this phase, sperm can swim into the fallopian tubes within minutes of ejaculation and wait there for the egg or fertilize an existing egg.

Normally, only one egg matures per cycle because it prevents further growth of the other eggs. Whether an egg in the right or left ovary makes the race happens by chance and is not controlled separately. If there is only one ovary left, it simply takes over the task of the other one, so that ovulation can continue to take place in every cycle.

If, exceptionally, more than one ovary jumps, the ovulations take place within a few hours of each other. This does not change the duration of the fertile phase. The chance that all of the ovulated eggs will be fertilized and subsequently successfully implant in the uterine mucosa is very low.

As a rule, ovulation occurs 10 to 16 days before the next menstrual period - so the second half of the cycle is about the same for all healthy women.  Incorrectly, the mid-cycle or the 14th day of the cycle is sometimes assumed to be the time of ovulation. However, this would only sometimes be the case even with a very regular 28-day cycle. Furthermore, it has been shown that a 28-day cycle occurs in only about 13% of cycles in healthy women. And thus ovulation actually occurs on the 14th or 15th day of the cycle in only about 25% of women. However, in 60% of women ovulation occurs after the 14th day of the cycle and in about 5% of women ovulation occurs on the 11th day of the cycle or earlier.

Determine ovulation or calculate ovulation?

So you see, a simple determination of your ovulation based on a calendar (calendar method) only works if you have a very regular 28-day cycle. And even then it is more of an estimate than a real calculation. If you want to calculate your ovulation and it is important to you that the result is really accurate, you should study your body and the processes during your menstrual cycle a little beforehand. This is because your body sends you signs which you can use to determine which phase of the cycle you are currently in.

Phases of the female cycle

1st cycle phase: the egg matures

From the first day of your period until ovulation, you are in the egg maturation or follicular phase. During this time, a new follicle begins to grow and the lining of the uterus begins to build up. When egg maturation and the renewed build-up of the uterine lining begin varies from woman to woman. For some women, this process begins immediately after the last menstrual period, while for others there is a break of a few days or even weeks in between.

The ovulation phase: alternation between the cycle phases

The day of ovulation is not really a phase in its own right, but simply marks the transition from the first half of the cycle to the second half. It is the moment of follicle rupture, when the mature egg is transferred into the fallopian tube. This time is characterized by a very special cocktail of hormones that triggers ovulation and raises the basal body temperature by about 32,36 °F. Some women can also feel ovulation: they experience it as a more or less strong, stabbing or pulling pain, which sometimes lasts for several hours. This so-called mid-cycle pain (intermenstrual pain) can usually be localized on one side of the lower abdomen and occurs a few days before or as a direct result of ovulation.

2nd cycle phase: Fertilization or new cycle?

In the second phase of the cycle, the uterus continues to prepare for possible implantation. If the egg was fertilized in time by a sperm cell, it will move on to the uterus. Once there after a few days, it will bore into the uterine wall. If this is successful, a new life begins to grow. The hormones released during this process prevent menstruation as well as the maturation of further eggs.

If fertilization does not occur, the second half of the cycle ends with the shedding of the uterine lining and a new cycle begins with the onset of menstruation.

Measuring basal body temperature and calculating ovulation

A clear sign that ovulation has occurred is the increase in basal body temperature. The basal body temperature - also known as the internal body temperature - is measured at rest, i.e. preferably in the morning before you get up for the first time. To do this, you need a very accurate thermometer that can display the result to two decimal places. The measurement must be taken rectally or vaginally and should take at least five minutes so that the result is really accurate enough.

You then enter the measured values into a special temperature chart or an app for Natural Family Planning (NFP) and evaluate them according to fixed rules. If you have a very regular cycle, you can use this method to narrow down your fertile days. This can be enough to have a better chance of getting pregnant. However, with this method you can only recognize ovulation in retrospect - for an ovulation prognosis you must first observe your cycle over a longer period (about 6-12 months).

Ovulation process: step by step

At birth, the ovaries contain about 1-2 million eggs. Each egg is surrounded by a companion cell and together they form the follicle. Once a woman is fertile, 10-20 follicles mature in the ovary each cycle. The onset and duration of the egg maturation phase varies greatly from individual to individual and can vary from cycle to cycle. In addition to genetic factors, stress or illness can also have an influence on the egg maturation phase. During the egg maturation phase, one follicle continues to develop and grows into a mature variant. All remaining follicles are converted into connective tissue and are thus "used up". Oocytes, unlike male sperm cells, cannot be re-formed. Therefore, in women shortly before menopause, the supply is usually already used up.

Egg maturation and ovulation are controlled by a complex regulatory system with several hormones. Follicle stimulating hormone (FSH) plays a central role in these processes. The follicle that is ready to jump increases its estradiol production, which in turn leads to a sudden release of a large amount of lutenizing hormone (LH). This large increase in hormone leads to ovulation about 24 hours later.

During ovulation, the follicle pushes the ovarian wall outward. At the bulge, enzymes then cause the walls of the ovarian follicle and any connective tissue to break down. Once this has happened, the follicle empties and the egg it contains is expelled and absorbed by the oviduct. The remains of the follicle are transformed into the so-called corpus luteum, which plays an important role in the further hormonal balance.

Everything about ovulation / ovulation at a glance:

  • At birth: 1-2 million eggs
  • Oocyte + accompanying cell = follicle
  • 10-20 follicles mature per cycle
  • Duration of the egg maturation phase varies greatly
  • Dominant follicle triggers ovulation
  • Oocyte is actively released into the oviduct
  • Follicle remnant is transformed into corpus luteum
  • Ovulation usually 10-16 days before next menstrual period

What happens after follicle rupture?

If the egg cell is not fertilized by a male sperm cell in the outer third of the oviduct within a maximum of 18 hours, it dies and is absorbed. About 10-16 days after ovulation, menstruation begins, also due to a finely tuned interplay of various hormones, and the ovarian cycle (menstrual cycle) starts all over again.

If, on the other hand, the egg is fertilized and can subsequently implant in the uterine wall, pregnancy occurs. During pregnancy, hormones released by the embryo prevent further eggs from maturing. In addition, the cervix closes and the cervical mucus becomes firm and viscous, making it almost impossible for sperm to pass through.

Use ovulation calculator: fast, easy, accurate

Many women find the manual method of calculating ovulation time-consuming and annoying. Since the method only works if it is really done consistently and meticulously, it creates quite a lot of pressure, which can have a negative impact on your desire to have children. So if you feel stressed anyway because it hasn't worked out yet, an ovulation calculator is certainly the more convenient and time-saving option.

Our Lady-Comp or Pearly ovulation calculators make it particularly easy for you to calculate your fertility: all you have to do is measure your basal body temperature under your tongue once in the morning for 60 seconds. That's it! You can dispense with all further observations, examinations and measurements with a clear conscience.

Lady-Comp or Pearly - accurate and reliable!

Our ovulation calculators work with a highly developed, unique algorithm, which was developed from the evaluation of over five million cycles. The accuracy has been confirmed again and again in studies. When using our ovulation computers, you only have to make sure that you had at least 3-4 hours of restful night sleep before the measurement and that you measure before getting up the very first morning. The comfortable time window of 6 (+3/+3) hours, for example, gives you the possibility to sleep in on the weekend without affecting your measurements.
