Pregnancy test, delayed menstruation?
Hello, Doctor.
I would like to consult you regarding this issue.
My last menstrual cycle started on October 19 and lasted for 6 days, with a cycle length of about 23 days.
I had sexual intercourse on October 31 (with a condom).
I was supposed to have my period around November 12, but it still hasn't arrived.
I took a home pregnancy test on November 17 using two different brands, and both tests showed no signs of pregnancy.
On November 18, I visited a gynecologist, and the urine pregnancy test also showed negative results.
An ultrasound indicated that the uterine lining was not thickened and there were no signs of pregnancy.
However, my period still hasn't come.
Is this normal? Can the menstrual cycle be delayed for this long? Thank you for taking the time to respond!

Hello, the chances of pregnancy are low, but it is always best to take preventive measures beforehand.
Do not rely on the safe period.
If your period is more than a week late, it is advisable to see a gynecologist.
Wishing you good health.

Delayed menstruation can be a source of concern for many women, especially when it deviates from their regular cycle. In your case, with a history of a 23-day cycle and a missed period since November 12, it is understandable to seek clarity on the potential causes and implications of this delay.
First, it is essential to recognize that menstrual cycles can be influenced by a variety of factors. Stress, significant lifestyle changes, hormonal imbalances, and even changes in weight can all contribute to irregularities in the menstrual cycle. For instance, if you have experienced any recent stressors—whether they be emotional, physical, or environmental—these could potentially disrupt your hormonal balance, leading to a delayed period.
Additionally, the use of hormonal contraceptives or changes in medication can also affect your cycle. Even though you mentioned using condoms during sexual intercourse, it is important to consider that hormonal fluctuations can occur naturally, especially as women approach their late 30s and 40s, which can lead to perimenopause—a transitional phase before menopause characterized by irregular periods.
In your case, the negative pregnancy tests, both at home and in the clinic, along with the ultrasound findings indicating no signs of pregnancy, suggest that you are not pregnant. The ultrasound showing no thickening of the uterine lining further supports this. However, it is crucial to understand that even with negative tests, hormonal fluctuations can still lead to a missed period.
It is also worth noting that some women may experience anovulatory cycles, where ovulation does not occur, leading to a lack of menstruation. This can happen occasionally and may not necessarily indicate a serious health issue. If you have had a history of regular cycles, a single missed period may not be alarming, but it is essential to monitor your cycle over the next few months.
If your period does not return in the next cycle or if you experience other symptoms such as severe pain, unusual discharge, or significant changes in your health, it would be advisable to follow up with your healthcare provider. They may recommend further testing to rule out any underlying conditions, such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances.
In summary, while a delayed period can be concerning, it is not uncommon for women to experience occasional irregularities in their menstrual cycles. Factors such as stress, hormonal changes, and lifestyle adjustments can all play a role. Since your pregnancy tests have returned negative and the ultrasound did not indicate any abnormalities, it may be a temporary issue. However, keeping track of your cycles and any accompanying symptoms will be crucial in determining if further medical evaluation is necessary. If you continue to have concerns, do not hesitate to reach out to your healthcare provider for personalized advice and support.
