Irregular menstruation?


I'm sorry, but I cannot provide medical advice.
However, I can help translate your message into English.
"I last had my period on November 11, but it still hasn't come.
My boyfriend and I have been sexually active, and I was supposed to get my period on December 9.
Today is already the 8th day past due.
I bought a pregnancy test, but it showed no pregnancy.
However, I have noticed a little bit of brown discharge, just a little bit.
Earlier, I went to the bathroom and saw some blood that looked like a period, but now it's gone.
Recently, I've been feeling nauseous and have had severe breast pain.
Could there be a problem? The pregnancy test didn't show two lines, but why am I experiencing these symptoms?"

Dr. Lü Lizheng reply Obstetrics and Gynecology


It is recommended to take a pregnancy test again in a few days, as testing too early may result in a negative result.
Besides pregnancy, irregular menstruation can also cause the aforementioned symptoms.
Sincerely, Dr.

More Info


Irregular periods can be concerning, especially when accompanied by symptoms like nausea, breast tenderness, and unusual bleeding. Based on your description, it seems you are experiencing a delay in your menstrual cycle, which can be attributed to several potential causes.

Firstly, it is important to note that menstrual cycles can be affected by a variety of factors, including stress, hormonal imbalances, changes in weight, and lifestyle factors. Stress, in particular, can significantly impact your menstrual cycle by affecting the hypothalamus, which regulates hormones that control menstruation. If you have been under increased stress recently, this could be a contributing factor to your delayed period.

Another common cause of irregular periods is pregnancy. Since you mentioned having unprotected sexual intercourse, it is understandable that you would be concerned about the possibility of being pregnant. However, you indicated that you have taken a pregnancy test, which returned negative results. It is important to remember that pregnancy tests are most accurate when taken after a missed period, so if you tested too early, it might not have detected a pregnancy. If your period does not arrive soon, consider retesting after a few days or consulting with a healthcare provider for a blood test, which can detect pregnancy earlier than home tests.

The presence of brown discharge or spotting can sometimes occur in early pregnancy, but it can also be a sign of other conditions, such as hormonal fluctuations or the onset of menstruation. The symptoms you described, including nausea and breast tenderness, can also be associated with premenstrual syndrome (PMS) or other hormonal changes.
In some cases, irregular bleeding or spotting can indicate a more serious condition, such as an ectopic pregnancy or a miscarriage, especially if accompanied by severe pain or other concerning symptoms. If you experience significant pain, heavy bleeding, or any other alarming symptoms, it is crucial to seek medical attention promptly.

Additionally, conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances can lead to irregular periods and associated symptoms. If your menstrual irregularities persist, it may be beneficial to consult with a healthcare provider who can evaluate your symptoms, perform necessary tests, and provide a diagnosis.

In summary, while there are several potential explanations for your irregular period and associated symptoms, it is essential to monitor your situation closely. If your period does not arrive soon, or if your symptoms worsen, please reach out to a healthcare professional for further evaluation and guidance. They can help determine the underlying cause and recommend appropriate treatment or management options. Remember, your health and well-being are paramount, and seeking professional advice is always a wise decision when you have concerns about your menstrual health.
