excuse me?

Is it possible for having sex a week before my period to delay my period? It's already the time when my period is supposed to arrive, but it hasn't come yet! We used a condom during intercourse, and I pulled out before ejaculation, so I didn't ejaculate inside the condom.
Is there a chance I could be pregnant?

More Info

Intercourse before menstruation does not directly delay your period. The menstrual cycle is regulated by hormonal changes in your body, and while sexual activity can influence some aspects of your cycle, it does not typically cause a delay in menstruation. If you are experiencing a delay in your period, there are several factors to consider.

Firstly, it is important to understand that the menstrual cycle can be affected by various factors including stress, changes in weight, exercise levels, and hormonal fluctuations. If you have been under stress or have made significant lifestyle changes, these could contribute to a delay in your period. Additionally, if you have recently started or changed any form of hormonal contraception, this could also impact your cycle.

Regarding your specific situation, you mentioned that you had intercourse with a condom and withdrew before ejaculation. This method, when done correctly, significantly reduces the risk of pregnancy. However, no contraceptive method is 100% effective, and there is always a small chance of pregnancy, especially if the condom was not used properly or if it broke. If you are concerned about the possibility of pregnancy, it may be wise to take a home pregnancy test. These tests are most accurate when taken after a missed period.

If your period is late and you have ruled out pregnancy, it may be beneficial to consult with a healthcare provider. They can help determine if there are any underlying issues that need to be addressed. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances can lead to irregularities in your menstrual cycle.

In summary, while intercourse before your expected period does not cause a delay, various factors can influence your menstrual cycle. If you are experiencing a delay, consider the potential causes and consult with a healthcare professional if necessary. It is always best to stay informed about your reproductive health and seek guidance when you have concerns.
