Delayed Menstruation: Pregnancy or Underlying Issues?

Delayed menstruation?

Hello Doctor, the last time I had sexual intercourse was on October 8th.
I noticed some slight blood streaks when wiping after urinating on October 7th and October 10th.
My period is normally due on October 18th, but I visited a traditional Chinese medicine doctor on October 22nd, who informed me that my period would come after I had it.
However, my period still hasn't arrived.
I took a home pregnancy test on October 24th, which showed one line, but I have been experiencing breast tenderness.
Could you please advise whether I might be pregnant or not? My menstrual cycle tends to be unstable, often fluctuating every two months.
Is there a problem with my uterus? Thank you, Doctor.

Hello, the chances of getting pregnant are low, but it's always best to take preventive measures beforehand.
Do not rely on the safe period.
If your period does not arrive within another week, it is advisable to see a gynecologist.
Wishing you good health.

More Info

Delayed menstruation can be a source of anxiety and confusion, especially when trying to determine whether it indicates pregnancy or an underlying health issue. Based on your situation, where your last sexual encounter was on October 8 and you expected your period around October 18, but it has not yet arrived, there are several factors to consider.

Firstly, the presence of slight blood when wiping on October 7 and 10 could indicate ovulation spotting or other hormonal fluctuations, but it is not definitive evidence of pregnancy. The fact that you took a home pregnancy test on October 24 and received a negative result (one line) suggests that you are not pregnant, especially if the test was taken correctly and within the appropriate timeframe after your missed period.

However, the symptoms you describe, such as breast tenderness and swelling, can be associated with premenstrual syndrome (PMS) or hormonal changes rather than pregnancy. It's also important to note that menstrual cycles can be irregular for various reasons, including stress, changes in weight, hormonal imbalances, or underlying medical conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders.

Given that your menstrual cycle has been irregular, with periods coming every two months, it would be wise to consult with a healthcare provider for a comprehensive evaluation. They may recommend blood tests to check hormone levels, including thyroid hormones, prolactin, and androgens, to rule out any hormonal imbalances. Additionally, an ultrasound may be performed to assess the ovaries and uterus for any structural issues.

If you are experiencing significant stress, as you mentioned, this can also impact your menstrual cycle. Stress can lead to elevated cortisol levels, which may disrupt the normal hormonal signals that regulate menstruation. Therefore, managing stress through relaxation techniques, exercise, and adequate sleep can be beneficial.

In summary, while the absence of your period may raise concerns about pregnancy, the negative pregnancy test and your symptoms suggest that other factors may be at play. It is essential to seek medical advice to explore the underlying causes of your irregular cycles and to discuss your symptoms in detail. A healthcare provider can help you navigate this situation and provide appropriate treatment options if necessary.
