5 signs of ovulation and why it matters


Most women don't know about their ovulation until they try to conceive. However, the state of the menstrual cycle and the presence of ovulation is one of the key signals that everything is functioning correctly in a woman's body. Let's talk about the main signs of ovulation and why the main moment of the cycle is not menstruation, but ovulation itself.

Ovulation, a fundamental element of womanhood?

So why is ovulation so important for us women? Let's give 3 brief examples.

  • Hormone balance
  • Estrogen and progesterone, the two main hormones regulating the cycle, should be in balance with each other. A large part of progesterone comes from the corpus luteum, a structure that forms from the remnants of the dominant follicle that released the mature egg. Ovulation is therefore essential for sufficient progesterone production in the second part of the cycle. If ovulation does not occur, progesterone levels can be very low, which will affect not only the course of the cycle and the balance of progesterone with estrogen.


  • Overall cycle progression
  • An imbalance of estrogen and progesterone can cause uncomfortable experiences, especially in the second part of the cycle, in the form of so-called premenstrual syndrome (PMS). If ovulation does not occur or occurs later, the follicular phase is prolonged, and thus the overall length of the cycle is also prolonged. In the long run, you may experience irregular menstruation or cycles longer than the typical 35 days.


  • Women's physical and mental health
  • The balance and adequate production of hormones extend far beyond fertility. Reproductive hormones influence, for example:

    • bone health
    • muscle growth and athletic performance
    • immune system function
    • brain health and function
    • mental health and body resilience

    Anovulatory cycles and hormone imbalances can then affect your overall health and daily functioning.

    Cycle at a glance

    The entire cycle is counted from the first day of menstruation. This day also marks the beginning of the follicular phase, during which the body releases follicle-stimulating hormone (FSH), which supports the maturation of the egg in the follicle and prepares it for early release. As ovulation approaches, the body produces luteinizing hormone (LH), which signals the release of a mature egg. On the day of ovulation, this egg leaves the ovary to be fertilized by sperm.

    After ovulation, the luteal phase begins; the hormone progesterone supports the thickening of the uterine lining in anticipation of a possible pregnancy. If fertilization does not occur during this time, menstruation begins, and the entire cycle repeats itself.


    5 signs of ovulation

    Increased basal body temperature

    Shortly after ovulation, the body releases progesterone hormone, which dominates the luteal phase. This leads to an increase in body temperature. Tracking your basal body temperature regularly each cycle can give you an idea of when ovulation typically occurs during your cycle.

    Change in cervical fluid

    The cervix produces a fluid called cervical mucus, which serves to cleanse the female body and, in particular, facilitates sperm access to a mature egg. The surge in hormones, specifically estrogen, just before ovulation increases the secretion of this fluid. During fertile days, the fluid becomes thinner and more elastic, often being compared to egg white in consistency. (1)

    Mild lower abdominal pain

    This sign is not typical for all women and may not even appear in every cycle. During ovulation, you may experience a temporary sharp pain or cramp on one side of your lower abdomen. So-called Mittelschmerz, as ovulatory pain is often called, coincides with peak LH levels when the follicle enlarges but has not yet ruptured and released the egg. It can therefore occur just before ovulation. It does not necessarily have to appear at the moment the egg is released from the ovary, but several hours to days before or after ovulation. (2) However, the pain should only be short-term; if you experience it regularly, it lasts several hours, or it completely prevents you from normal activities, it is advisable to consult a doctor.

    Increased sex drive

    Due to the surge in luteinizing hormone (LH) that occurs 24-36 hours before ovulation, you may also experience an increased sex drive. This is your body's way of indicating that it supports conception. (3)

    Ovulation spotting or bleeding

    Although not very common, some women experience light bleeding or spotting during ovulation. This is probably related to higher levels of progesterone and luteinizing hormone. (4) It usually involves a few drops of light red or pink blood and no menstrual protection is needed at this time.

    Mid-cycle spotting can also be caused by other factors, such as hormonal contraception, pregnancy, or fibroids. (5) If you regularly experience heavy bleeding during ovulation, consider contacting your gynecologist.

    How long is the fertile window?

    An egg released from the ovary survives in the female body for 12-24 hours. However, sperm can survive in the female body for several days and wait for the moment the egg is ready. The so-called fertile window, during which you can conceive, is thus calculated as 3-7 days before ovulation and 1 day after ovulation. However, every woman may have a different menstrual length, so it is necessary to know yourself and your cycle to determine your fertile days.


    How to track your cycle?

    By measuring basal body temperature and tracking cervical mucus, you can easily determine your fertile window, and also understand your cycle and find out if everything is working as it should in your body. The so-called symptothermal method can be used both for planning pregnancy and as a natural form of contraception.

    Frequently Asked Questions

    How to support fertility naturally?

    A healthy diet, sufficient exercise, sleep, stress management, and targeted dietary supplements like folic acid or a fertility complex can naturally support female fertility.

    When should I start taking folic acid?

    We recommend starting folic acid ideally 3 months before planned conception. It is crucial for the proper development of the fetal neural tube.

    What affects female fertility?

    Age, hormonal balance, diet, body weight, stress, and conditions like PCOS or endometriosis can affect fertility. Tracking ovulation will help you identify fertile days.
