Feel like yourself again with a healthy cycle. We’re here to support you.
Irregular periods, severe pain, or other symptoms can often feel like something you just have to live with. But your cycle gives important insights into your health.
Cycle-related symptoms aren’t simply “normal.” They’re a sign — and that sign should be taken seriously.
We take the time to understand your story, analyze your cycle, and look closely for the underlying causes. This way, we don’t just treat symptoms — we work toward a lasting solution.
“ Years of severe menstrual pain — finally free of symptoms thanks to the right diagnosis. ”
From puberty to menopause, your cycle is constantly changing. Hormonal fluctuations can lead to symptoms such as abdominal pain, cramps, fatigue, and mood swings. With insight into your cycle and targeted support, you can reduce symptoms and help your cycle stay balanced — so your body can function at its best throughout every stage of life.
A hormonal imbalance occurs when estrogen, progesterone, and other hormones are not in balance. This can disrupt your cycle and cause symptoms such as irregular periods, abdominal pain, fatigue, and mood swings. With a better understanding of your cycle, your lifestyle, and targeted treatment, you can support your hormonal balance and help your body return to balance.
Polycystic ovary syndrome (PCOS) often leads to irregular menstrual cycles, acne, weight gain, hair loss, and reduced fertility. It is caused by hormonal imbalances and is often linked to insulin resistance. Symptoms can vary from person to person, develop gradually, and differ in severity — affecting energy levels, mood, and overall well-being.
Symptoms during menopause are caused by declining estrogen levels. Common symptoms include hot flashes, night sweats, mood swings, sleep problems, and fatigue. The type and severity of symptoms vary from person to person. A healthy lifestyle and targeted medical treatment can help provide lasting relief.
Endometriosis is a chronic inflammatory condition that can cause severe menstrual pain, abdominal and pelvic pain, fatigue, and fertility problems. Symptoms often worsen around menstruation and can significantly impact daily life. We treat these symptoms while preserving your natural cycle.
We help women with cycle-related symptoms by analyzing their cycle and addressing hormonal imbalances, combined with lifestyle improvements for greater balance and better health.
Personal stories from women and couples we’ve had the privilege of supporting.
Many women ask themselves: “What does my menstrual cycle say about my health?” or “When are cycle-related symptoms still normal?” The menstrual cycle is an important indicator of hormonal balance and can provide valuable information about your overall health.
Cycle-related symptoms are common and can appear in different ways. These may include menstrual pain, heavy or prolonged bleeding, premenstrual symptoms such as mood swings, irritability or low mood, menstrual migraines, fatigue, sleep problems, bloating, or breast tenderness. These symptoms may be mild, but they can also be strong enough to affect daily life.
By systematically recording these symptoms within your cycle, it becomes clear when they occur and how they relate to hormonal fluctuations. This helps you recognize patterns and distinguish which symptoms are still within the normal range and which may point to a hormonal imbalance or other underlying factors.
FertilityCare support focuses on carefully interpreting these cycle patterns and symptoms. This makes it clearer when observation is sufficient and when further diagnostics or treatment may be useful. In this way, your cycle becomes a valuable tool for better understanding and more specifically supporting your health.
Many women intuitively feel that their cycle influences how they feel, think, and function, but often lack the knowledge to truly understand these signals. FertilityCare is a scientifically grounded method that helps you understand your cycle and fertility from within.
You learn to consciously observe your body’s biological signals, recognize patterns, and discover what is personally normal for you. This gives you insight into your fertile days and helps you plan the timing of a pregnancy more intentionally.
“Why has no one ever explained this to me before?” is a question FertilityCare instructors often hear. Many women experience that their cycle affects their well-being, but they do not have the knowledge to interpret these changes systematically.
FertilityCare offers a structured and scientifically grounded way to make the physiological processes of your cycle visible and understandable. By carefully observing and recording biomarkers, you learn to recognize patterns and identify possible abnormalities. This makes it possible not only to track your cycle, but also to analyse it.
But FertilityCare is about more than fertility alone. It helps you look at your body with greater confidence and make informed choices about your health, your cycle, and your family planning. In a way, you learn to speak the “language” of your body — and above all, to understand it.
This knowledge can be especially valuable if you experience symptoms such as irregular or painful cycles, have an unfulfilled desire to conceive, or feel uncertain about what your body is trying to tell you. This systematic approach is particularly helpful for symptoms such as irregular or painful cycles, subfertility, or uncertainty about physical signals.
By charting the cycle, a more objective and medically grounded understanding of your hormonal health can emerge. What may sometimes feel as though your body is failing you can gradually become more understandable, predictable, and medically clearer.
A menstrual cycle lasts on average between 25 and 35 days. Within this physiological range, variations are often normal. However, changes in regularity, duration, or pattern may be clinically relevant and deserve attention and observation.
By systematically charting your cycle and associated symptoms, you gain insight into your personal cycle pattern. This helps you better distinguish normal variations from possible abnormalities, such as oligomenorrhea, polymenorrhea, or a persistently irregular cycle pattern.
The menstrual cycle consists of three consecutive phases, regulated by a carefully coordinated interaction between brain and ovarian hormones, known as the HPO axis. These hormonal fluctuations influence not only the ovaries and uterus, but the entire body. They can affect energy levels, temperature regulation, mood, and physical sensations.
In this way, the menstrual cycle forms an interconnected physiological process in which different body systems are closely linked through hormonal regulation.
1. Follicular phase
The cycle begins with menstruation, during which the uterine lining is shed. Estrogen and progesterone levels are low, which may be associated with lower energy levels.
In the ovary, an egg begins to mature within a follicle. This follicle produces estrogens, preparing the body for a possible pregnancy: the uterine lining thickens and cervical mucus changes. Estrogen gradually rises, and many women experience more energy, mental clarity, and an improved overall sense of well-being.
2. Ovulatory phase
An LH surge triggers the release of the egg. During this phase, a woman may observe a typical vaginal discharge for several days: cervical mucus. Under the influence of estrogen from the mature follicle, this mucus becomes thinner, clearer, and more elastic.
This mucus helps sperm pass through the cervix and can nourish them and prolong their survival. This change is often clearly recognizable because the mucus feels and looks different from other moments in the cycle.
This is the most fertile phase of the cycle and is often accompanied by a feeling of increased vitality.
3. Luteal phase
After ovulation, the follicle changes into the corpus luteum, which produces progesterone. This hormone further prepares the body for a possible pregnancy by supporting the uterine lining and closing the cervix.
If fertilization does not occur, the corpus luteum disappears, hormone production drops, and the uterine lining is shed — the new cycle begins.
By understanding and carefully observing bodily signals, or “biomarkers,” relevant deviations can be recognized early and treated if necessary.

Video material is also available, explaining the method and its scientific background in an accessible way.
The course begins with a non-binding introductory session, during which the method is explained step by step using a presentation. This meeting provides time to explain the approach, answer questions, and explore together what the method could mean for you.
This is followed by a course consisting of eight private sessions. These can take place either online or in person. During this phase, you will gradually learn how to observe, record, and interpret your cycle according to the FertilityCare method.
There is a strong focus on personal guidance, ensuring that the method fits well into your daily life.
As the course progresses, the content is further deepened and adapted to your personal situation — for example, in cases of a desire to conceive, cycle-related symptoms, breastfeeding, or the transition into perimenopause.
The course is not a standalone program, but part of a broader medical-diagnostic approach. It serves as both a foundation for understanding your cycle and a starting point for further care, where medical treatment and personal guidance are closely aligned.
To get started, you can contact one of the FertilityCare instructors for an introductory meeting.
FertilityCare is a suitable method for the diagnosis and treatment of premenstrual syndrome (PMS), premenstrual dysphoric disorder (PMDD), and cycle-related mood symptoms.
Many women notice that symptoms such as irritability, low mood, anxiety, fatigue, or physical discomfort recur monthly, but the connection with the cycle is not always clear.
By carefully tracking the menstrual cycle and hormonal changes across its phases, it becomes clearer why symptoms often occur in the second half of the cycle. At the same time, this observation helps identify recurring patterns, for example when mood swings, crying spells, or mental fatigue consistently occur in the same phase.
Within FertilityCare, the cycle is not only tracked but also systematically analysed. Through structured observation and guidance, you learn to better understand your body’s signals and place them in context.
This often brings recognition and relief: symptoms are not “imagined,” but frequently have a clear hormonal and physical basis.
This cycle knowledge forms the foundation for targeted diagnostics. Depending on the symptoms, additional laboratory testing may be performed, such as hormone levels (e.g. estradiol and progesterone), thyroid function, prolactin, cortisol, and metabolic markers.
Based on these insights, an individual treatment plan is developed. If needed, medication may be used, such as bioidentical hormones like progesterone in the luteal phase in cases of deficiency or imbalance.
If hormonal factors are not the primary cause, other contributors are considered, such as stress, sleep disturbances, HPA-axis dysregulation, or metabolic imbalances, which can be treated accordingly.
Nutrition, targeted micronutrient supplementation, and lifestyle factors such as sleep, exercise, and stress regulation also play an important role, as they have a proven effect on hormonal balance and emotional well-being.
The FertilityCare approach is structured and fully tailored to your individual situation, within a gynecological-endocrinological framework. Diagnostics and treatment are closely coordinated and regularly evaluated.
The goal is a sustainable reduction of symptoms and restoration of emotional balance, based on a better understanding of your body and a medically grounded treatment approach.
During perimenopause, cycle observation can also provide valuable insight into what is happening in the body. Menstruation often becomes lighter and more irregular, mood swings less predictable, and symptoms such as fatigue, inner restlessness, insomnia, and concentration difficulties may increase.
Weight fluctuations and changes in body shape can also affect self-image. In a time of many changes, this understanding can offer important support.
By systematically tracking these changes, a clearer understanding of the natural course of hormonal transition emerges. This helps distinguish normal physiological changes from symptoms that may require further diagnostics or treatment.
Depending on the symptoms, a wide range of individualized treatment options is available. These take into account not only the nature and severity of symptoms, but also personal needs during this life phase, daily life impact, medical history, and individual risk factors.
If necessary, hormonal therapy may be considered, often in the form of bioidentical hormones such as estradiol and progesterone. These correspond to the body’s own hormones and can help reduce symptoms such as hot flashes, sleep problems, and mood changes.
Together, it is carefully evaluated whether such treatment is appropriate, taking into account medical history, personal risks, and preferences.
Existing conditions such as cardiovascular disease, metabolic disorders, or bone health are also considered in treatment. Care takes place under gynecological-endocrinological supervision to ensure safe and well-considered diagnostics and treatment.
If hormonal therapy is not suitable or desired, non-hormonal alternatives are also available. These may include certain medications, as well as complementary approaches such as phytotherapy and targeted use of micronutrients.
Lifestyle guidance also plays an important role. Nutrition, sleep, stress management, and physical activity can make a significant difference to overall well-being.
All steps are coordinated together to create a treatment approach that is both medically sound and aligned with your personal situation and needs in this life phase.
Many women with endometriosis experience symptoms such as severe menstrual pain, pelvic pain, pain during or after intercourse, and symptoms such as fatigue or a heavy, bloated feeling.
By systematically tracking these symptoms within your cycle using FertilityCare, it becomes clear in which phases they occur and how they relate to hormonal changes.
This insight can serve as the basis for further medical guidance. Together with your doctor, your cycle data and symptom patterns are reviewed to assess whether additional diagnostic testing is needed, for example to better visualize endometriosis or rule out other causes.
Based on this, a personalized treatment plan can be developed. This may include medical treatments such as hormonal therapy or pain management, and, if necessary, further specialist care. At the same time, attention is given to improving your overall cycle health and reducing symptoms in daily life.
In this way, a coherent approach is created in which your experience is central. Your symptoms are not viewed in isolation, but in relation to your cycle, allowing for step-by-step progress toward greater understanding, stability, and targeted treatment.
Many women experience a wide range of symptoms related to their menstrual cycle. These can vary from spotting or irregular bleeding patterns to long or very short cycles, heavy menstrual bleeding (menorrhagia), or very light periods.
Painful menstruation (dysmenorrhea) is also common, often accompanied by lower abdominal cramps, back pain, nausea, or pain radiating to the legs.
In addition, many symptoms occur during the luteal phase — the days or weeks before menstruation. These may include irritability, low mood, anxiety, mood swings, increased sensitivity to stress, fatigue, sleep problems, and cognitive symptoms such as difficulty concentrating or “brain fog” (PMS or, in more severe cases, PMDD).
Other common symptoms include migraines, headaches, breast tenderness, fluid retention, and bloating, often following a cyclical pattern.
When these symptoms recur consistently or affect quality of life, they may indicate an underlying hormonal imbalance or other gynecological conditions, such as endometriosis, adenomyosis, PCOS, or ovulatory disorders.
FertilityCare supports the systematic tracking of these symptoms in relation to the cycle, allowing patterns to become visible and better understood. This forms the basis for further clinical evaluation.
Depending on the findings, different medical treatment options may be considered, following a step-by-step, medically grounded approach in which symptoms are not viewed in isolation, but in connection with the cycle.
