Missed menstruation?


My last menstrual period ended on June 11.
I had sexual intercourse on June 18, using a condom that did not break.
Around July 6, I visited a gynecologist for a pregnancy test and ultrasound, and there were no signs of pregnancy.
On July 15, I noticed my period was still delayed, so I went back to see the doctor.
He prescribed a three-day course of medication, which I started taking that same day, but my period still hasn't arrived.
I've been experiencing breast pain for a long time, and my lower abdomen has started to hurt intermittently, but my period still hasn't come.
What should I do?

Answer: After visiting the doctor on July 15 for a pregnancy test and ultrasound, which showed no signs of pregnancy, you were prescribed a three-day course of medication.
Your period is expected to arrive between July 20 and 24.
If your period has not started by July 31, you should return to see the doctor.

Understanding delayed menstruation can be a complex issue, as it can stem from various causes, and it is essential to consider both physiological and psychological factors. In your case, you mentioned that your last menstrual period ended on June 7, and you had unprotected intercourse on June 11 and June 18, although you used a condom that did not break. You also took a pregnancy test and had an ultrasound on July 6, which showed no signs of pregnancy. However, by July 15, your menstruation was still delayed, prompting another visit to the doctor, who prescribed medication to induce menstruation.

There are several potential reasons for delayed menstruation beyond pregnancy, including:
1. Hormonal Imbalances: The menstrual cycle is regulated by a complex interplay of hormones. Any disruption in this balance, whether due to stress, weight changes, or underlying health conditions, can lead to delayed periods.

2. Stress and Anxiety: Psychological factors such as stress and anxiety can significantly impact your menstrual cycle. High levels of stress can lead to hormonal changes that may delay ovulation and menstruation.

3. Weight Fluctuations: Significant weight loss or gain can affect your menstrual cycle. Low body weight, particularly in athletes or those with eating disorders, can lead to missed periods.

4. Polycystic Ovary Syndrome (PCOS): This common hormonal disorder can cause irregular periods, among other symptoms. It is characterized by enlarged ovaries containing small cysts and can lead to hormonal imbalances.

5. Thyroid Issues: Both hyperthyroidism and hypothyroidism can affect menstrual cycles. Thyroid hormones play a crucial role in regulating the menstrual cycle, and any dysfunction can lead to delays.

6. Medications: Certain medications, including hormonal contraceptives and some psychiatric medications, can influence menstrual regularity.

7. Underlying Health Conditions: Conditions such as uterine fibroids, endometriosis, or pelvic inflammatory disease can also cause menstrual irregularities.

Given that you have been experiencing breast tenderness and intermittent lower abdominal pain, it is essential to follow up with your healthcare provider. The medication prescribed to induce menstruation should typically result in a period within a few days. If your period does not arrive after completing the medication, it is crucial to return to your doctor for further evaluation.

Here are some steps you can take moving forward:
- Monitor Symptoms: Keep track of any additional symptoms you may experience, such as changes in mood, weight, or other physical symptoms. This information can be helpful for your healthcare provider.

- Follow-Up Appointment: Schedule a follow-up appointment with your gynecologist. They may recommend further testing, such as blood tests to check hormone levels, or imaging studies to rule out any anatomical issues.

- Lifestyle Adjustments: Consider lifestyle factors that may be affecting your menstrual cycle. This includes managing stress through relaxation techniques, maintaining a balanced diet, and ensuring regular physical activity.

- Consider a Second Opinion: If you feel your concerns are not being adequately addressed, seeking a second opinion from another healthcare provider can provide additional insights.

In summary, while delayed menstruation can be concerning, it is essential to approach it with a comprehensive understanding of potential causes. Working closely with your healthcare provider will help you navigate this issue effectively and determine the best course of action for your health.
