Suspected pregnancy?


Hello, doctor.
I had sexual intercourse with my boyfriend on August 17, but my menstrual period was from August 9 to August 14.
He did not fully penetrate, and there was no ejaculation.
I have taken pregnancy tests on August 31 and September 4, both showing one line.
Can I be assured that I am not pregnant? Additionally, in the past week or two, I have experienced some itching and redness at the vaginal opening, and I have had increased discharge.
Could this be related to the sexual activity? Thank you for your clarification.

Hello, the itching and redness at the vaginal opening, along with increased discharge, may indicate inflammation.
If you have had unprotected intercourse, it is advisable to take preventive measures against pregnancy.
If you continue to experience discomfort, it is recommended to consult a gynecologist.
Wishing you good health.

When it comes to understanding pregnancy doubts, particularly regarding testing and symptoms, it’s essential to consider several factors, including the timing of tests, the nature of symptoms, and the reliability of pregnancy tests.

Based on your timeline, you had sexual intercourse around August 17, following your menstrual period from August 9 to August 14. Since you mentioned that there was no ejaculation and that penetration was not complete, the likelihood of pregnancy from that encounter is significantly reduced. Pregnancy tests are designed to detect the hormone hCG (human chorionic gonadotropin), which is produced shortly after a fertilized egg attaches to the uterine lining. Typically, hCG levels can be detected in urine about 14 days after conception, which aligns with your testing dates of August 31 and September 4.

The fact that both tests returned a single line indicates that no hCG was detected, suggesting that you are not pregnant. However, it’s important to note that home pregnancy tests can sometimes yield false negatives, especially if taken too early. Given your timeline, it seems unlikely that you are pregnant, but if your period does not arrive as expected, it would be advisable to retest or consult a healthcare provider for further evaluation.

Regarding the symptoms you mentioned—itching and redness around the vaginal area, along with increased discharge—these could be related to several factors, including a possible yeast infection or bacterial vaginosis, which can occur after sexual activity. Changes in vaginal discharge, especially if accompanied by itching or irritation, often indicate an imbalance in the vaginal flora or an infection. It’s crucial to monitor these symptoms; if they persist or worsen, seeking medical advice would be prudent. A healthcare provider can perform a physical examination and possibly a swab test to determine the underlying cause and recommend appropriate treatment.

In summary, based on the information provided, it appears that you are not pregnant, especially given the negative results from the pregnancy tests. However, the symptoms you are experiencing warrant attention. It’s always best to err on the side of caution and consult with a healthcare professional if you have ongoing concerns about your reproductive health or if you experience any unusual symptoms. Regular check-ups and open communication with your healthcare provider can help ensure that any potential issues are addressed promptly and effectively.
