A delay of 12 days in menstruation raises the possibility of pregnancy?
Hello, Doctor.
The app indicates that my period was due on August 7, but it has been delayed for 12 days.
I purchased pregnancy tests on August 11 and 12, both showing negative results.
I visited a gynecologist on August 13, where the pregnancy test was also negative, and the doctor performed an ultrasound, which did not show any signs of pregnancy or abnormalities in the ovaries.
The doctor prescribed medication to induce menstruation.
However, I am still concerned about the possibility of being pregnant and whether taking the medication could harm the fetus if I am indeed pregnant.
I have a chronic condition: hyperthyroidism, which is being managed with medication.
My menstrual cycles have been: July 8 to July 11, June 7 to June 11, May 10 to May 14, and April 11 to April 15.
I had sexual intercourse on August 2 (unprotected, ejaculation inside) and August 3 (unprotected, withdrawal method).
I would appreciate your insights on the likelihood of pregnancy and the appropriate timing for taking a pregnancy test.
Thank you, Doctor.

1.
For pregnancy concerns, please perform a home pregnancy test or visit a gynecologist for examination and evaluation four weeks after your most recent sexual intercourse.
2.
The menstrual cycle can be influenced by various psychological and physiological factors.
If your period is more than two months late, it is recommended to consult a gynecologist for examination and evaluation.

More Info
When it comes to understanding delayed periods and the potential for pregnancy, there are several factors to consider. Based on your situation, it appears that your menstrual cycle was expected to start on August 7, but it has been delayed for 12 days. You have taken home pregnancy tests on August 11 and 12, both of which returned negative results. Additionally, a visit to your gynecologist on August 13 confirmed that there was no evidence of pregnancy through both urine tests and ultrasound examination.
Understanding Delayed Periods
A delayed period can be caused by various factors, including stress, hormonal imbalances, changes in weight, excessive exercise, or underlying medical conditions. In your case, you mentioned having hyperthyroidism, which can significantly affect menstrual cycles. Thyroid hormones play a crucial role in regulating the menstrual cycle, and any imbalance can lead to irregularities.
Pregnancy Chances
Given that you had unprotected sexual intercourse on August 2 and 3, there is a possibility of pregnancy, especially if you have irregular cycles. However, the negative pregnancy tests and ultrasound findings suggest that pregnancy is unlikely. Home pregnancy tests are generally reliable when used correctly, especially after a missed period. They work by detecting the hormone human chorionic gonadotropin (hCG), which is produced shortly after a fertilized egg attaches to the uterine lining. If the tests are negative and your doctor has confirmed the absence of pregnancy through ultrasound, the likelihood of being pregnant is low.
Concerns About Medication
You expressed concern about the medication prescribed to induce menstruation (催經藥) and whether it could harm a potential fetus if you were indeed pregnant. It is crucial to communicate openly with your healthcare provider about your concerns. Generally, medications used to induce menstruation are not recommended during pregnancy as they can potentially lead to complications. However, since your doctor has confirmed that there is no pregnancy, the risk is minimal in your case.
Recommendations
1. Follow-Up with Your Doctor: Since you have a history of thyroid issues, it is essential to keep your healthcare provider informed about your menstrual irregularities. They may want to monitor your thyroid levels and adjust your medication if necessary.
2. Consider Timing for Pregnancy Tests: If you suspect you might be pregnant, it is advisable to wait a few days after a missed period before taking a home pregnancy test. This allows enough time for hCG levels to rise to a detectable level.
3. Monitor Symptoms: Keep track of any other symptoms you may experience, such as changes in mood, weight fluctuations, or any unusual physical symptoms. These can provide additional context for your healthcare provider.
4. Lifestyle Factors: Consider lifestyle factors that may contribute to menstrual irregularities, such as stress management, balanced nutrition, and regular exercise. These can have a positive impact on your overall reproductive health.
5. Seek Support: If you continue to experience anxiety regarding your menstrual cycle and potential pregnancy, consider speaking with a mental health professional or a support group. Emotional well-being is an essential aspect of reproductive health.
In summary, while the chances of pregnancy appear low based on your tests and ultrasound, it is essential to continue monitoring your health and communicating with your healthcare provider. They can provide personalized advice and support tailored to your specific situation.
