Her period is now almost 7 days late.
Is it possible that she is pregnant? Answer: Since we used a condom throughout the entire intercourse without any leakage, it is unlikely that she is pregnant.

When considering the possibility of pregnancy, especially after engaging in sexual activity with condom use, it’s essential to understand both the effectiveness of condoms and the factors that can lead to a delayed menstrual period.
Condoms are generally considered a reliable form of contraception when used correctly. According to the Centers for Disease Control and Prevention (CDC), male condoms have an effectiveness rate of about 85% with typical use, meaning that about 15 out of 100 women will become pregnant each year despite using condoms. However, if used perfectly, the effectiveness can be as high as 98%. This means that while the risk of pregnancy is significantly reduced with proper condom use, it is not entirely eliminated.

In your case, since you mentioned that the condom was used throughout the sexual encounter without any leakage, the likelihood of pregnancy is relatively low. However, it is crucial to consider other factors that could contribute to a missed or delayed period. Stress, hormonal imbalances, changes in weight, and lifestyle factors such as diet and exercise can all impact the menstrual cycle.
For example, if your girlfriend has been experiencing increased stress—perhaps due to exams or other life events—this could potentially delay her period. Stress can affect the hypothalamus, the part of the brain that regulates hormones responsible for the menstrual cycle. Additionally, if she has been experiencing significant changes in her routine, such as sleep patterns or physical activity levels, these could also contribute to a delay.

Given that her period is already a week late, it would be advisable for her to take a home pregnancy test. Most pregnancy tests are designed to detect the hormone hCG (human chorionic gonadotropin) in urine, which is produced shortly after a fertilized egg attaches to the uterine lining. For the most accurate results, it is recommended to wait until at least the first day of the missed period or about two weeks after potential conception. If the test is positive, it would confirm pregnancy; if negative and her period still does not arrive, she should consult a healthcare provider for further evaluation.

In summary, while the use of condoms significantly reduces the risk of pregnancy, it does not eliminate it entirely. Given the delay in her period, it is prudent for her to take a pregnancy test. If she continues to experience irregularities in her menstrual cycle or has concerns about her reproductive health, seeking advice from a healthcare professional would be beneficial. They can provide guidance on managing stress, lifestyle factors, and any necessary medical evaluations to ensure her overall health and well-being.
