Painful or Irregular Periods: When to Seek Medical Advice
Updated: Sep 10
A period that changes can feel unsettling—especially when pain, heavy bleeding or uncertainty begins to affect everyday life. Keeping a simple record of what is happening can make the next conversation with your healthcare professional much clearer.
What changes are worth noticing?
Cycles vary from person to person. What matters is your usual pattern and whether something has changed. Note the first day of each period, how long bleeding lasts, whether you are changing pads or tampons more often than usual, and how pain affects work, sleep or daily activities.
Speak with a doctor if your previously regular periods become irregular for several months, if your period stops for more than three months without an explanation, or if pain is severe enough to disrupt normal activities. Heavy bleeding that requires changing a pad or tampon every one to two hours, bleeding that lasts longer than seven days, dizziness or faintness also deserves medical attention. Sudden severe pelvic pain, especially with a possible pregnancy, should be assessed urgently.
Understanding the cause of a change
Painful or irregular periods can have many possible causes. These include changes in ovulation, thyroid conditions, polycystic ovary syndrome, fibroids, endometriosis, stress, changes in weight or exercise, and some medications. A doctor may take a medical history and recommend appropriate tests. Identifying the cause helps you make an informed decision about care.
The TCM approach to menstrual health
At Olive3, your TCM consultation considers cycle timing, bleeding, pain, sleep, digestion and other symptoms together. Depending on the assessed pattern, traditional principles may include nourishing Blood (the TCM concept of nourishment) or moving Qi and Blood (traditional concepts of functional activity and nourishment). Physician Koh explains the assessment and discusses suitable options, including acupuncture, individually prescribed Chinese medicine or daily routines.
Please tell both your TCM physician and your medical team about medicines, supplements and fertility treatments you are using. This is especially important if you are pregnant, trying to conceive, taking blood-thinning medicine, or preparing for a procedure.
Preparing for your consultation
You do not need a perfect record. A few notes can still help:
• the dates and length of your recent cycles
• where and when pain occurs
• the amount of bleeding and any spotting
• changes in sleep, digestion, stress or energy
• recent medical results, diagnoses and medicines
• what you most want help understanding
A calm, coordinated approach
Questions about periods are personal, and your consultation gives you time to explain what you are experiencing. Physician Koh consults in English and Mandarin, discusses your priorities and explains the proposed TCM care plan. Relevant information can be shared with other treating clinicians with your consent.
Frequently asked questions
What should I bring if my periods have changed?
Bring a cycle record, recent test results and your medication list if available. If symptoms suggest an underlying condition, arrange the recommended investigations; their findings provide useful context for your TCM care.
Can I attend while undergoing fertility treatment?
Discuss your TCM care and fertility treatment with both clinicians. Bring your treatment schedule and medication list so care can be coordinated appropriately.
How long will I need treatment?
Frequency and duration are personalised to your assessment, preferences, response and any other care you receive. Your physician agrees on review points with you and adjusts the plan where appropriate. Individual responses vary.
