Changes in Menstrual Flow: Causes and Concerns

Menstrual issues

Hello, doctor.
Previously, my menstrual period lasted for 7 days, and I experienced blood clots along with severe menstrual pain.
However, after taking traditional Chinese medicine, my symptoms have improved significantly, and I have had little to no menstrual pain in recent cycles.
My last period started on April 6, but this time the flow seems lighter than before, although there are still blood clots.
The blood is bright red, and by today (the fifth day), the flow has decreased significantly and has turned brown, which seems to indicate that my period is coming to an end.
I would like to ask the following questions:
1.
What could be the reason for the sudden decrease in menstrual flow? Could it be due to my high academic stress?
2.
I have read online that if the endometrial lining is not thick enough, the menstrual flow may decrease.
Is this true?
3.
If my period is not overdue (only delayed by 6 days) and there is a larger amount of bright red blood with clots, can I conclude that I am not pregnant?

Hello, the factors that can affect the menstrual blood volume in women may include hormonal imbalances, emotions, diet, age, and others.
However, it is crucial to rule out conditions such as uterine tumors, endometrial hyperplasia, cervical lesions, and vaginal lesions.
If symptoms persist or worsen, it is advisable to consult a physician for further evaluation.
Additionally, if there is uncertainty about whether the bleeding is a true menstrual period, it is important to check for pregnancy.
Thank you! Wishing you peace and health, Dr.
Chang.

Understanding changes in menstrual flow can be a complex issue, as it can be influenced by various factors, including hormonal fluctuations, lifestyle changes, and underlying health conditions. Let's address your concerns one by one.

1. Sudden Decrease in Menstrual Flow: A sudden change in menstrual flow, such as a decrease in blood volume, can be attributed to several factors. Stress, particularly academic pressure, can indeed affect your menstrual cycle. Stress triggers the release of cortisol, which can interfere with the hormonal balance necessary for regular menstruation. Additionally, changes in weight, diet, exercise habits, and even sleep patterns can also impact menstrual flow. If you have recently experienced significant stress or changes in your routine, this could be a contributing factor.

2. Endometrial Thickness and Menstrual Flow: The thickness of the endometrial lining (the inner lining of the uterus) plays a crucial role in menstrual flow. If the endometrial lining is not adequately developed, it can result in lighter menstrual bleeding. This condition can occur due to hormonal imbalances, particularly involving estrogen. If your body is not producing enough estrogen, the endometrial lining may not thicken sufficiently, leading to lighter periods. This is a valid concern, and if you suspect this might be the case, it would be wise to consult with a healthcare provider who can evaluate your hormonal levels and overall reproductive health.

3. Determining Pregnancy Status: The presence of bright red blood with clots during menstruation typically indicates a normal menstrual cycle rather than pregnancy. However, if you experience a delay in your period (even if it’s just six days) and have symptoms such as breast tenderness, nausea, or fatigue, it may be worth taking a pregnancy test for confirmation. Bright red blood is usually associated with fresh menstrual flow, while brown blood often indicates older blood that has taken longer to exit the uterus, which is common towards the end of a period. If you are concerned about the possibility of pregnancy, a home pregnancy test or a visit to your healthcare provider can provide clarity.

In summary, changes in menstrual flow can be influenced by a variety of factors, including stress, hormonal imbalances, and lifestyle changes. If you continue to experience irregularities in your menstrual cycle or have concerns about your reproductive health, it is advisable to seek a consultation with a healthcare professional. They can perform necessary evaluations, such as blood tests to check hormone levels or imaging studies to assess the health of your reproductive organs. Understanding your body and its responses is crucial, and professional guidance can help you navigate these changes effectively.
