Missed Period: Delays and Symptoms in Women's Health - Obstetrics and Gynecology

Missed menstruation?


My menstrual cycle is usually about 34-36 days.
The last period I had was from September 17 to September 21, and this month, the app predicted it would start on October 23, but it has been delayed and hasn’t arrived yet.
I have been experiencing some lower abdominal pain and breast tenderness.
Even though I have had sexual intercourse, I have used protection.
Now, my cycle has reached 46 days.
I’m wondering if this could be due to stress from exams a few weeks ago.
What should I do?

More Info


Missed periods can be a source of anxiety for many women, especially when they are accustomed to a regular menstrual cycle. In your case, you mentioned that your typical cycle ranges from 34 to 36 days, with your last period occurring from September 17 to September 21. Given that your period was expected around October 23 and has now been delayed for 46 days, it is understandable to be concerned about the reasons behind this delay.

Firstly, it's important to recognize that menstrual cycles can be influenced by a variety of factors, including stress, hormonal imbalances, changes in weight, and lifestyle factors. You mentioned experiencing stress due to exams, which can significantly impact your menstrual cycle. Stress activates the hypothalamus, which can disrupt the hormonal signals that regulate ovulation and menstruation. This disruption can lead to delayed or missed periods.

In addition to stress, other factors that can contribute to a missed period include:
1. Hormonal Changes: Fluctuations in hormones, particularly estrogen and progesterone, can affect the regularity of your menstrual cycle. Conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders can also lead to irregularities.

2. Lifestyle Factors: Changes in diet, exercise, and sleep patterns can have a profound impact on your menstrual cycle. For instance, significant weight loss or gain, excessive exercise, or irregular sleep can all lead to missed periods.

3. Pregnancy: Although you mentioned using protection during sexual intercourse, no contraceptive method is 100% effective. If there is any possibility of pregnancy, it would be advisable to take a home pregnancy test for confirmation.

4. Medical Conditions: Certain medical conditions, such as uterine fibroids, endometriosis, or pelvic inflammatory disease, can also cause changes in your menstrual cycle. If you have a history of such conditions, it may be worth consulting a healthcare provider.

Given your symptoms of lower abdominal pain and breast tenderness, it is also important to consider that these could be premenstrual symptoms or signs of hormonal changes. However, they could also indicate other conditions, so monitoring your symptoms is crucial.


What Should You Do Next?
1. Take a Pregnancy Test: If there is any chance of pregnancy, taking a home pregnancy test can provide clarity. If the test is negative and your period does not arrive, it may be worth consulting a healthcare provider.

2. Monitor Your Symptoms: Keep track of any additional symptoms you may experience, such as changes in mood, weight, or energy levels. This information can be helpful for your healthcare provider.

3. Manage Stress: Since stress can significantly affect your menstrual cycle, consider incorporating stress-reducing techniques into your routine. This could include mindfulness practices, yoga, or other relaxation techniques.

4. Consult a Healthcare Provider: If your period does not return in the next few weeks, or if you experience severe pain or other concerning symptoms, it is advisable to seek medical advice. A healthcare provider can perform necessary evaluations, including blood tests to check hormone levels, and provide guidance based on your individual health needs.

In summary, while a missed period can be concerning, it is often related to manageable factors such as stress or hormonal fluctuations. By taking proactive steps and consulting with a healthcare provider if necessary, you can gain a better understanding of your menstrual health and address any underlying issues.
