Having two menstrual periods in one month?


Hello Doctor: My menstrual period started on February 5, which was normal timing.
However, the flow was quite thick, and I did not experience any discomfort, just that the menstrual flow was concentrated in the first two days, and then it was lighter for the next five days.
The color was darker than usual, with more blood clots and thickness.
After that, I felt a little bit of residual flow until the 11th.
Then, there were two to three days of relatively clean discharge, but still some remnants.
On the morning of February 16, I noticed blood streaks in my vaginal discharge, which startled me because I have never experienced this since my first period.
For four days, from February 16 to 19, there was a small amount of brownish discharge.
I visited a doctor on the evening of the 16th and had a pelvic examination.
The doctor diagnosed me with cervicitis and prescribed medication for vaginal inflammation.
However, the discharge continued to have some discoloration for four days.
Then, on the morning of February 20, my period unexpectedly returned, and by the 21st, the flow was heavy, similar to my usual menstrual flow, accompanied by abdominal pain and frequent gas.
Could you please tell me if I have any underlying conditions? I am 33 years old, and I started having sexual experiences after getting married in September 2005.
I have never had irregular periods before this year.
In January 2006, I sought medical attention for pelvic pain, which was diagnosed as pelvic inflammatory disease.

Hello: It may just be irregular menstruation, but an ultrasound, pelvic examination, Pap smear, and pregnancy test should still be performed to rule out potential gynecological conditions that could cause bleeding.

More Info


Understanding irregular periods can be a complex issue for many women, as it often involves a variety of physiological, hormonal, and lifestyle factors. Based on the information provided, it appears that you have experienced a range of symptoms associated with your menstrual cycle, including changes in flow, color, and consistency, as well as the occurrence of spotting between periods.
Firstly, it is important to recognize that menstrual cycles can vary significantly from month to month due to numerous factors. These can include stress, changes in weight, hormonal fluctuations, and underlying health conditions. In your case, the thick and dark menstrual flow, along with the presence of blood-tinged discharge, could indicate several possibilities.

One common cause of irregular periods is hormonal imbalance. Hormones such as estrogen and progesterone play crucial roles in regulating the menstrual cycle. When these hormones are out of balance, it can lead to changes in the menstrual cycle, including heavier or lighter periods, longer or shorter cycles, and spotting between periods. Conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can also contribute to irregularities in the menstrual cycle.

The presence of thick, dark menstrual blood can sometimes be a sign of retained blood, which may occur if the menstrual flow is particularly heavy or if there are uterine fibroids or polyps present. These growths can cause changes in the menstrual cycle and may lead to heavier bleeding or clotting. It is also worth noting that the color of menstrual blood can vary; darker blood is often older blood that has taken longer to exit the uterus.

Spotting between periods, particularly if it is accompanied by other symptoms such as abdominal pain or discomfort, can be indicative of several conditions. In your case, the diagnosis of cervical inflammation (cervicitis) could explain some of the spotting and discomfort you are experiencing. Cervicitis can be caused by infections, sexually transmitted infections, or other irritants, and it may lead to abnormal bleeding.

Given your history of pelvic inflammatory disease (PID), it is essential to monitor your symptoms closely. PID can lead to scarring and changes in the reproductive organs, which may contribute to irregular menstrual cycles and other complications. If you experience persistent irregularities, significant pain, or other concerning symptoms, it is crucial to seek further evaluation from a healthcare provider. This may include imaging studies, blood tests, or further gynecological examinations to rule out any serious underlying conditions.

In summary, while irregular periods can be concerning, they are often manageable with appropriate medical care. It is essential to maintain open communication with your healthcare provider about your symptoms and any changes you notice in your menstrual cycle. Regular check-ups and monitoring can help ensure that any potential issues are addressed promptly, allowing you to maintain your reproductive health and overall well-being. If you have further questions or concerns, do not hesitate to reach out to a healthcare professional for personalized advice and treatment options.
