May I ask the doctor?

Hello! I would like to ask a question.
In the past, my menstrual cycle was not very regular; sometimes it would only come once every one or two months, and other times it would return about ten days after it just ended, but the flow was not heavy.
I consulted a traditional Chinese medicine practitioner, who said that this was intermenstrual bleeding.
After taking medication, this situation improved.
However, starting a few months ago, my menstrual intervals have been almost eleven to twelve days, and this month is the same.
The difference from previous months is that this month the flow is light and seems to last only one or two days.
Is this still considered a menstrual period or intermenstrual bleeding? Could there be other underlying causes? Additionally, if my menstrual intervals have indeed changed to every ten days instead of the typical 28 days, should I see a doctor to regulate my cycle? Or is it acceptable as long as it is consistent? Thank you for your response!

Dear Netizen: Hello! Menstrual blood in women is the result of the shedding of the uterine lining, influenced by hormones after ovulation when pregnancy does not occur.
Most women have a regular ovulation cycle of about 28-30 days, which is why it is referred to as menstruation.
However, some women may experience irregular ovulation cycles due to physiological factors, leading to irregular menstrual cycles.
It is common for some women to experience varying degrees of uterine lining shedding and bleeding during ovulation due to fluctuations in female hormones, known as ovulation bleeding or intermenstrual bleeding.
A normal menstrual cycle following ovulation should not be less than 21 days.
Based on your description, it is possible that you are experiencing simple irregular menstrual cycles and intermenstrual bleeding.
However, not all uterine or vaginal bleeding is classified as menstrual blood.
Abnormal uterine bleeding may also be an early symptom of certain diseases, which should not be overlooked.
Therefore, it is advisable for you to consult a nearby obstetrician-gynecologist for an examination to rule out any gynecological conditions before treating the irregular menstrual cycle.

More Info

Irregular menstrual cycles can be a source of concern for many women, and understanding when to seek medical advice is crucial for maintaining reproductive health. Based on your description, it seems you have experienced significant fluctuations in your menstrual cycle, with periods occurring as frequently as every 11-12 days and sometimes with light flow. Here’s a comprehensive overview of what might be happening and when you should consider consulting a healthcare provider.

Understanding Your Menstrual Cycle
A typical menstrual cycle lasts about 28 days, but it can vary from 21 to 35 days in adults. Irregularities can manifest in various forms, including:
1. Oligomenorrhea: Infrequent menstrual periods, typically defined as cycles longer than 35 days.

2. Polymenorrhea: Frequent menstrual periods, occurring less than 21 days apart.

3. Amenorrhea: The absence of menstruation for three months or more.

4. Menorrhagia: Heavy or prolonged menstrual bleeding.

Given your history of irregular cycles and the recent changes, it’s important to differentiate between normal variations and potential underlying issues.

Possible Causes of Irregular Menstrual Cycles
Several factors can contribute to irregular menstrual cycles, including:
- Hormonal Imbalances: Conditions like polycystic ovary syndrome (PCOS), thyroid disorders, or changes in estrogen and progesterone levels can disrupt your cycle.

- Stress and Lifestyle Factors: High stress, significant weight changes, excessive exercise, or poor diet can affect hormonal balance and menstrual regularity.

- Medications: Certain medications, including hormonal contraceptives, can alter your cycle.

- Underlying Health Conditions: Conditions such as endometriosis or uterine fibroids can lead to irregular bleeding patterns.

When to Seek Medical Advice
Given your situation, here are some guidelines on when to consult a healthcare provider:
1. Persistent Irregularities: If your menstrual cycle continues to be irregular (e.g., periods occurring every 11-12 days) over several months, it’s advisable to seek medical advice. A healthcare provider can help determine if there’s an underlying hormonal imbalance or other health issues.

2. Changes in Flow: If you notice significant changes in the volume or duration of your menstrual flow, such as very light periods or spotting between cycles, this warrants further investigation.

3. Associated Symptoms: If you experience additional symptoms such as severe pain, excessive bleeding, or signs of hormonal imbalance (e.g., weight gain, acne, excessive hair growth), it’s essential to consult a healthcare professional.

4. Impact on Daily Life: If your menstrual irregularities are affecting your quality of life, such as causing anxiety or impacting your ability to plan activities, it’s a good idea to seek help.

What to Expect During a Medical Consultation
When you visit a healthcare provider, they may perform several evaluations, including:
- Medical History Review: Discussing your menstrual history, lifestyle factors, and any associated symptoms.

- Physical Examination: A pelvic exam may be conducted to check for any abnormalities.

- Blood Tests: Hormonal levels, thyroid function tests, and other relevant blood tests may be ordered.

- Imaging Studies: In some cases, ultrasound or other imaging studies may be necessary to evaluate the reproductive organs.

Conclusion
In summary, while occasional irregularities in your menstrual cycle can be normal, persistent changes or associated symptoms should prompt a visit to a healthcare provider. Early intervention can help identify any underlying issues and provide appropriate treatment options, ensuring your reproductive health is maintained. Remember, it’s always better to err on the side of caution when it comes to your health.
