Irregular Periods and Breast Changes: Possible Causes and Concerns

How did it swell and then disappear?

Dear Doctor, I had my period on June 11, and then I had sexual intercourse around June 20.
My most recent period started on July 8, and I had unprotected sex on July 10 for less than 5 minutes.
My menstrual flow in the past two months has been slightly lighter than usual.
I have been drinking iced beverages frequently and staying up late.
Additionally, I did not experience breast tenderness before both of these periods, but surprisingly, I experienced breast engorgement on July 17, which lasted for 5 days and then disappeared.
I have also been experiencing frequent diarrhea and abdominal pain lately.
Why did the breast engorgement come and go? This has never happened to me before.
Could you please help me? Thank you! What is the likelihood of pregnancy in this situation? I would appreciate any analysis or guidance you can provide.

Hello, the question you raised has been addressed in the previous response: the description you provided cannot be used as a reliable reference to determine if there is a pregnancy.
It is best to consult a physician for an ultrasound and urine test; otherwise, no matter how much more complex the inquiry becomes, a definitive diagnosis cannot be established.
Thank you! Wishing you peace and health.
Dr.
Chang.

Understanding irregular periods and breast changes can be quite complex, as various factors can influence both menstrual cycles and breast health. Based on your description, it seems you are experiencing several symptoms that could be linked to hormonal fluctuations, lifestyle changes, and possibly stress.

Firstly, it's important to note that menstrual cycles can vary significantly from month to month due to a variety of factors, including stress, diet, exercise, and hormonal changes. The fact that your periods have become lighter could be attributed to these factors. Additionally, lifestyle habits such as consuming cold drinks frequently and staying up late can affect your overall hormonal balance, potentially leading to irregularities in your menstrual cycle.

Regarding the breast changes you mentioned, such as the sudden onset of breast engorgement (or "milk" production) after a period of absence, this can also be linked to hormonal fluctuations. The hormone prolactin, which is responsible for milk production, can sometimes be elevated due to stress or other hormonal imbalances, even in women who are not pregnant or breastfeeding. This could explain why you experienced breast engorgement for five days and then it subsided.
The occurrence of breast tenderness or engorgement is often cyclical and can be influenced by the menstrual cycle. Typically, many women experience breast tenderness in the luteal phase (the time between ovulation and the start of menstruation) due to increased levels of estrogen and progesterone. However, if you are not experiencing the usual symptoms leading up to your period, it could indicate a shift in your hormonal levels.

As for the gastrointestinal symptoms you mentioned, such as diarrhea and abdominal pain, these can also be related to hormonal changes, particularly during the menstrual cycle. Some women experience gastrointestinal disturbances as a part of premenstrual syndrome (PMS) or due to other underlying conditions.

Regarding your concerns about pregnancy, the risk of pregnancy is present whenever unprotected intercourse occurs, regardless of the duration. If you are concerned about the possibility of being pregnant, it would be advisable to take a home pregnancy test, especially if your period is delayed or if you experience other early signs of pregnancy, such as nausea or fatigue.

In summary, your symptoms could be attributed to a combination of hormonal fluctuations, lifestyle factors, and possibly stress. If your irregular periods and breast changes continue or worsen, or if you have any other concerning symptoms, it would be prudent to consult with a healthcare provider. They can perform a thorough evaluation, including a physical examination and possibly blood tests to assess hormone levels, and provide you with personalized advice and treatment options.

In the meantime, consider maintaining a healthy lifestyle, including a balanced diet, regular exercise, and adequate sleep, which can help regulate your menstrual cycle and improve overall well-being.
