The pregnancy test on November 23, which is more than 18 days after the sexual intercourse on October 10, should be able to detect a pregnancy if one were present.
Since the test result indicates that there is no pregnancy, we can trust the result.
The delayed menstruation may be due to irregularities in the menstrual cycle, and medical treatment can be sought.
Sincerely, Dr.

More Info

When it comes to the possibility of pregnancy, understanding the risks and symptoms is crucial. Based on your timeline, you had unprotected intercourse on October 10, shortly after your girlfriend's menstrual period ended. The fact that you withdrew before ejaculation (the "pull-out" method) does reduce the likelihood of pregnancy, but it is not a foolproof method. Sperm can sometimes be present in pre-ejaculate fluid, which means there is still a risk of pregnancy.

Your girlfriend experienced a menstrual period from November 2 to November 6, albeit with lighter flow on the fourth day. This could indicate a few things: it might be a normal variation in her menstrual cycle, or it could be an early sign of pregnancy, especially if her cycles are typically regular. The fact that you conducted pregnancy tests on November 16 and November 23, both returning negative results, suggests that she was likely not pregnant at that time. However, it is important to note that pregnancy tests are most accurate when taken after a missed period.

You mentioned that her period has not yet arrived this month, which could be a cause for concern. There are several reasons why a menstrual cycle might be delayed, including stress, hormonal imbalances, changes in weight, or other health issues. Given that she has been experiencing symptoms related to a yeast infection, it’s possible that her body is responding to that condition, which could also affect her menstrual cycle.

If her period does not arrive soon, it would be advisable for her to take another pregnancy test, ideally a few days after the expected date of her period. If the test is still negative and her period does not come, it would be wise for her to consult with a healthcare provider. They can perform a more sensitive blood test for pregnancy and evaluate any other potential underlying issues that might be affecting her menstrual cycle.

In summary, while the risk of pregnancy exists due to the nature of unprotected intercourse, the negative pregnancy tests and the occurrence of a menstrual period in early November suggest that pregnancy is less likely. However, the absence of her period this month warrants further investigation. Encourage her to monitor her symptoms and seek medical advice if her period does not resume or if she has any other concerning symptoms.
