excuse me?


Doctor Lu, may I ask: Is it concerning that I haven't come in for a month and only returned on November 13? What could be the reason for this? Do I need to see a doctor?

LL, 20~29 year old female. Ask Date: 2009/11/16

Dr. Lü Lizheng reply Obstetrics and Gynecology


Hello: When menstruation is delayed, the first consideration should be whether pregnancy has occurred.
If there has been no sexual intercourse recently, or if menstruation has clearly started later, pregnancy can be ruled out.
Otherwise, if there is only irregular or light bleeding, pregnancy is still a possibility, and a pregnancy test should be taken.
Additionally, a delayed period may be due to external factors disrupting the normal functioning of hormones, commonly referred to as hormonal imbalance or irregular menstruation.
For example, recent insomnia, exams, moving, changing jobs, arguments, stress, weight loss, travel, and so on can all contribute to this.
Mild irregularities can be monitored to see if the next period returns to normal.
However, severe menstrual irregularities, such as a period lasting more than 10 days, heavy bleeding lasting two to three days, continuous instability for three months, or significant abdominal pain, may indicate a more serious issue or other underlying problems.
In such cases, it is essential to consult a gynecologist for examination.
Wishing you peace and health.
Sincerely, Dr.
Li-Cheng Lu, Attending Physician, Department of Obstetrics and Gynecology, Taoyuan General Hospital, Ministry of Health and Welfare.

More Info


If you have missed your period for an entire month and are experiencing changes in your menstrual cycle, it is important to consider several factors before deciding whether to see a doctor. A missed period can be caused by a variety of reasons, including hormonal imbalances, stress, significant weight changes, excessive exercise, or underlying medical conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders.
In your case, since you mentioned that your period only arrived on November 13 after a month of absence, it is essential to evaluate any accompanying symptoms you may have experienced during this time. For instance, if you have had any unusual symptoms such as severe abdominal pain, excessive bleeding, or other significant changes in your health, it would be advisable to seek medical attention.
Additionally, if you are sexually active and there is a possibility of pregnancy, it is crucial to take a pregnancy test to rule out this possibility. Even if the test is negative, if your period remains irregular or if you continue to miss periods, it is wise to consult with a healthcare provider. They can perform a thorough evaluation, which may include a physical examination, blood tests to check hormone levels, and possibly imaging studies to assess your reproductive organs.

In general, if you experience a missed period along with other concerning symptoms or if your menstrual cycle has been consistently irregular, it is best to schedule an appointment with a gynecologist. They can help identify the underlying cause of your irregularities and recommend appropriate treatment options.
Moreover, lifestyle factors can also play a significant role in menstrual health. High levels of stress, changes in diet, and lack of exercise can all contribute to irregular periods. Therefore, it might be beneficial to assess your lifestyle and make any necessary adjustments, such as incorporating stress-reducing activities like yoga or meditation, maintaining a balanced diet, and ensuring you get enough physical activity.

In summary, while a missed period can sometimes be a normal occurrence, especially if it is an isolated incident, it is essential to monitor your body and any changes closely. If you have concerns about your menstrual health, do not hesitate to reach out to a healthcare professional for guidance. They can provide you with the necessary support and treatment to help regulate your menstrual cycle and address any underlying issues.
