Menstrual issues?


Hello Dr.
Liang: I got my first period at the age of 15, and initially, I did not experience any pain.
Now that I am 27, I have started to experience menstrual cramps, but they are mild and not severe.
My menstrual flow is normal.
I would like to ask the doctor if it is normal to pass some small blood clots when I go to the bathroom during my period, although it is not a lot.
My menstrual cycle is regular and comes on schedule.
Is this normal?

Juan, 20~29 year old female. Ask Date: 2005/03/10

Dr. Liang Yinpan reply Obstetrics and Gynecology


Hello Miss Juan! You started experiencing dysmenorrhea 12 years after your first menstruation, which is referred to as secondary dysmenorrhea.
This is generally caused by pelvic pathology, with endometriosis being the most common condition.
If your dysmenorrhea symptoms are becoming increasingly severe, you should promptly consult a gynecologist for further evaluation and treatment.
During the second and third days of menstruation, when menstrual flow is heavier, blood clots may sometimes form due to the inability to dissolve the menstrual blood quickly.
As long as the flow does not become excessively heavy and your menstrual cycle remains regular, there is usually no cause for concern.
Wishing you good health.

Menstrual issues, including the presence of blood clots during menstruation, are common concerns among women. It is important to understand that experiencing blood clots during your menstrual period can be normal, but it can also indicate underlying health issues depending on various factors.

Firstly, it is essential to recognize that menstrual blood can vary in consistency and appearance. Blood clots are typically formed when blood pools in the uterus and thickens before being expelled. This can happen for several reasons, including hormonal fluctuations, the flow rate of menstrual blood, and the overall health of the uterine lining. In many cases, small blood clots (about the size of a quarter or smaller) are considered normal and can occur without any cause for concern.

In your case, since you mentioned that your menstrual cycle is regular and you have been experiencing only mild discomfort, it is likely that the blood clots you are observing are within the normal range. However, there are certain situations where the presence of blood clots may warrant further investigation:
1. Size and Frequency of Clots: If you notice that the clots are larger than a quarter or if you are passing clots frequently throughout your period, this could indicate a heavier menstrual flow (menorrhagia) or other issues such as fibroids or polyps.

2. Associated Symptoms: If you experience additional symptoms such as severe pain, excessive bleeding (soaking through a pad or tampon every hour), or if the clots are accompanied by unusual symptoms like fever or foul-smelling discharge, it is advisable to consult a healthcare provider. These could be signs of conditions such as endometriosis, pelvic inflammatory disease, or other reproductive health issues.

3. Changes in Your Cycle: Since you have had a regular cycle until now, any sudden changes in your menstrual pattern, such as increased pain, changes in the duration of your period, or changes in the amount of blood, should be discussed with a healthcare professional.

4. Age and Health History: At 27 years old, if you have not experienced significant menstrual issues before, it is important to monitor any changes. If you have a family history of reproductive health issues or if you have other health conditions, it may be beneficial to have a discussion with your doctor.

In conclusion, while experiencing blood clots during your menstrual period can be normal, it is crucial to pay attention to the size, frequency, and any accompanying symptoms. If you have any concerns or if your menstrual pattern changes significantly, it is always best to consult with a healthcare provider for a thorough evaluation. They may recommend tests such as an ultrasound or blood tests to rule out any underlying conditions. Regular gynecological check-ups are also essential for maintaining reproductive health and addressing any concerns that may arise.
