Pregnancy test questions?


Hello, I would like to ask, after having sexual intercourse, I took a pregnancy test 22 days later and it showed one line, indicating no pregnancy.
I went to the obstetrician and took another pregnancy test, which also showed one line.
An ultrasound was performed, and the doctor confirmed that I am not pregnant.
Can I be certain that I am not pregnant? Additionally, my period is one month late; could this be due to hormonal imbalance? (The obstetrician did not inform me whether it is a hormonal imbalance or another condition, but prescribed medication to induce menstruation.)

zero zero, 20~29 year old female. Ask Date: 2016/03/21

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, a pregnancy test should be taken at least 12 days after conception for accurate results.
The chances of pregnancy are low, so it's best to use contraception beforehand.
If your period is more than a week late, consider consulting a gynecologist.
Wishing you good health.

When it comes to understanding pregnancy tests and menstrual irregularities, it's essential to consider several factors that can influence the results and the overall health of a woman. Based on your situation, where you have taken multiple pregnancy tests that returned negative results and have undergone an ultrasound that confirmed no pregnancy, it is reasonable to conclude that you are not pregnant. Pregnancy tests, whether urine or blood tests, are generally reliable when taken correctly and at the appropriate time.
Urine tests, like the ones you took, measure the presence of human chorionic gonadotropin (hCG), a hormone produced during pregnancy. If you tested negative 22 days after potential conception and again shortly after, it indicates that hCG levels are not elevated, which typically suggests that pregnancy is unlikely. Ultrasound examinations can also provide valuable insights, as they can visualize the uterus and confirm whether a gestational sac is present. If the ultrasound indicated no signs of pregnancy, this further supports the conclusion that you are not pregnant.

Regarding your menstrual irregularity, a delay of one month can indeed be attributed to various factors, including hormonal imbalances, stress, changes in weight, or underlying health conditions. The term "endocrine disorder" refers to any condition that affects hormone levels and can lead to irregular menstrual cycles. However, without further testing or a detailed medical history, it is challenging to definitively diagnose the cause of your delayed period.

If your gynecologist prescribed medication to induce your period, this is a common practice to help regulate menstrual cycles. It is essential to follow up with your healthcare provider if your periods remain irregular or if you experience other concerning symptoms. They may recommend additional tests, such as blood tests to check hormone levels, or imaging studies to assess the ovaries and uterus for any abnormalities.

In summary, based on the information provided, it appears that you are not pregnant, and the delay in your menstrual cycle could be due to various factors, including hormonal imbalances. It is advisable to maintain open communication with your healthcare provider to monitor your menstrual health and address any concerns you may have. Regular check-ups and discussions about your menstrual cycle can help identify any underlying issues and ensure that you receive appropriate care.
