Can I get pregnant?
Hello doctor, I would like to ask about my last menstrual period which was from June 14 to June 20.
I used condoms on July 1 and July 3, but I had unprotected intercourse briefly on July 2, with ejaculation outside.
Is there a chance of pregnancy? My app predicted my period would start on July 12, but it hasn't arrived by July 15.
My average menstrual cycle is 31 days, and my average period lasts 7 days.
If I want to take a pregnancy test, when would be the best time to do so for accurate results?

Hello, a pregnancy test should be taken at least 12 days after conception for accurate results.
It is best to use contraception to prevent pregnancy.
If your period is more than a week late, it is advisable to consult a gynecologist.
Wishing you good health.

More Info
When considering the possibility of pregnancy, it's essential to understand the timing of ovulation, the menstrual cycle, and the effectiveness of contraceptive methods. Based on your provided details, your last menstrual period was from June 14 to June 20, and you had unprotected intercourse on July 2, which is crucial for assessing your risk of pregnancy.
Understanding Your Cycle and Ovulation
A typical menstrual cycle lasts about 28 days, but it can vary significantly among individuals. You mentioned an average cycle length of 31 days, which means you likely ovulate around 14 to 17 days after the first day of your last period. In your case, if your cycle is 31 days, ovulation would likely occur around June 28 to July 1. Since you had unprotected intercourse on July 2, this timing is close to your ovulation window, which increases the risk of pregnancy.
Risk of Pregnancy
The risk of pregnancy from unprotected intercourse depends on several factors, including the timing of the intercourse relative to ovulation and the use of contraceptives. In your case, since you had intercourse just after your estimated ovulation period, there is a possibility of pregnancy. However, since you also used condoms on July 1 and July 3, this reduces the risk, as condoms are effective in preventing pregnancy when used correctly.
When to Test for Pregnancy
If your menstrual cycle is typically 31 days and your period was expected on July 12, you should wait until at least a few days after your missed period to take a home pregnancy test for the most accurate results. This is because pregnancy tests detect the hormone hCG (human chorionic gonadotropin), which is produced after a fertilized egg implants in the uterus. Implantation usually occurs about 6 to 10 days after conception, and hCG levels take time to rise to detectable levels.
Therefore, testing on or after July 15 would be advisable. If the test is negative and your period still does not arrive, consider retesting a few days later or consulting a healthcare provider for further evaluation.
Additional Considerations
If you experience any unusual symptoms, such as severe abdominal pain, heavy bleeding, or other concerning signs, it is essential to seek medical attention promptly. Additionally, if you find yourself frequently in situations where you are unsure about the effectiveness of your contraceptive methods, it may be beneficial to discuss long-term contraceptive options with your healthcare provider.
In summary, based on your menstrual cycle and the timing of intercourse, there is a possibility of pregnancy. Waiting until after your expected period to take a pregnancy test will provide the most reliable results. If you have further concerns or questions, do not hesitate to reach out to a healthcare professional for personalized advice and support.
