MC has not arrived yet?


Hello~ My menstrual cycle used to be very regular, and I didn't experience any pain when my period came.
However, in the past couple of months, my period has been late.
Last December, my period started around December 7, and this January, it started on January 15.
Now it is already February 20, and my period still hasn't arrived.
Is this normal? Thank you.

Hello: Please first take a pregnancy test and undergo an ultrasound along with other relevant examinations.
If the pregnancy test is negative and all related tests show no abnormalities, the most common causes of irregular menstruation are still stress and anxiety.

More Info


Irregular menstrual cycles can be concerning, especially when they deviate from what is considered normal for you. Based on your description, it appears that your menstrual cycle has become increasingly irregular, with significant delays in the onset of your periods. Your last menstrual period was on December 7, and you noted that your January period did not arrive until January 15. Now, as of February 20, you have yet to see your period.
First, it's important to understand what constitutes a normal menstrual cycle. A typical cycle ranges from 21 to 35 days, with an average of around 28 days. However, variations can occur due to several factors, including stress, hormonal imbalances, lifestyle changes, and underlying health conditions.
Given that your cycles were previously regular, the recent changes could be attributed to several factors:
1. Stress and Lifestyle Changes: Significant life changes, such as changes in work, school, or personal relationships, can impact your menstrual cycle. Stress can lead to hormonal fluctuations that may delay ovulation or menstruation.

2. Hormonal Imbalances: Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances can lead to irregular periods. These conditions can affect ovulation and the regularity of your menstrual cycle.

3. Weight Changes: Significant weight loss or gain can also impact your menstrual cycle. Body fat plays a role in hormone production, and changes in body weight can lead to irregularities.

4. Medical Conditions: Certain medical conditions, such as uterine fibroids or endometriosis, can cause changes in menstrual patterns. If you have any accompanying symptoms, such as pain, heavy bleeding, or unusual discharge, it is essential to discuss these with your healthcare provider.

5. Birth Control: If you are using hormonal birth control, it can also affect your cycle. Some forms of birth control can lead to lighter periods or even missed periods altogether.

Given your situation, it is advisable to seek help from a gynecologist, especially since your menstrual cycle has become irregular over the past few months. A gynecologist can perform a thorough evaluation, which may include:
- A detailed medical history and physical examination.

- Blood tests to check hormone levels, thyroid function, and other relevant markers.

- An ultrasound to assess the reproductive organs for any abnormalities.

Early intervention is crucial, especially if there are underlying health issues that need to be addressed. Your gynecologist can provide guidance on potential treatment options, which may include lifestyle modifications, hormonal treatments, or other interventions based on the underlying cause of your irregular periods.

In summary, while occasional irregularities in menstrual cycles can be normal, persistent changes warrant a consultation with a healthcare professional. It is essential to address any concerns you may have about your menstrual health to ensure that any potential issues are identified and managed appropriately.
