Q: Irregular Menstrual Cycles: Causes and When to Seek Help

Hello： Menstrual irregularities are most likely caused by functional hormonal imbalances, but a hospital examination is necessary to determine the cause. <br>Since you are unmarried, an ultrasound examination may be performed first.

What has been going on with the menstrual cycle for such a long time?

Hello Doctor: My menstrual cycle is very irregular.
I remember that it was only a week since my last period, and now my period has come again.
It has been almost two weeks and has not stopped yet.
The flow is dark in color and has a strong odor.
What could be the problem? If I seek medical attention, what kind of tests should I undergo? Thank you!

Irregular menstrual cycles can be a source of concern for many women, and your symptoms certainly warrant attention. Menstrual irregularities can manifest in various ways, including changes in cycle length, flow, and the characteristics of menstrual blood. In your case, experiencing a menstrual period that comes just a week after the last one and lasts for nearly two weeks, accompanied by dark-colored blood with a strong odor, suggests that there may be an underlying issue that needs to be addressed.

Several factors can contribute to irregular menstrual cycles. These include hormonal imbalances, stress, significant weight changes, excessive exercise, and underlying medical conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or uterine abnormalities like fibroids or polyps. Hormonal fluctuations, particularly involving estrogen and progesterone, play a crucial role in regulating the menstrual cycle. When these hormones are out of balance, it can lead to irregularities.

The dark color of your menstrual blood may indicate older blood that has taken longer to exit the body, which can happen during prolonged periods. However, the strong odor is concerning and could suggest the presence of an infection, such as bacterial vaginosis or a sexually transmitted infection (STI). Infections can also lead to changes in menstrual patterns and should be evaluated by a healthcare professional.

Given your symptoms, it is advisable to seek medical attention. When you visit a healthcare provider, they will likely perform a thorough evaluation, which may include:
1. Medical History: Discussing your menstrual history, any recent changes in lifestyle, stress levels, and any other symptoms you may be experiencing.

2. Physical Examination: A pelvic exam may be conducted to check for any abnormalities in the reproductive organs.

3. Blood Tests: These can help assess hormone levels, thyroid function, and check for anemia or signs of infection.

4. Ultrasound: A pelvic ultrasound may be performed to visualize the uterus and ovaries, helping to identify any structural issues such as fibroids or cysts.

5. Additional Tests: Depending on the initial findings, further tests may be necessary to rule out specific conditions.

It is essential to address these symptoms promptly, as they can impact your overall health and well-being. Irregular menstrual cycles can sometimes indicate more serious health issues, so early intervention is key.
In summary, your irregular menstrual cycles, particularly with the characteristics you've described, should be evaluated by a healthcare professional. They will guide you through the necessary tests and help determine the underlying cause of your symptoms. Don't hesitate to seek help, as understanding and addressing menstrual irregularities can lead to better health outcomes and peace of mind.
