Missed menstruation?

Hello doctor, my menstrual periods were from July 2 to July 8, August 7 to August 13, and September 15 to September 21.
I haven't gotten my period this month yet, and I've been experiencing breast tenderness for a week.
I had unprotected intercourse on October 6 and 8.

More Info

Based on the information you've provided, it is indeed possible that you could be pregnant after having unprotected sex. Given your menstrual cycle dates, it appears that your last period was from September 15 to September 21, and since you mentioned that your period for October has not yet arrived, you are currently experiencing a missed period.
In a typical menstrual cycle, ovulation usually occurs about 14 days before the start of your next period. If we consider your cycle length to be around 30 days, ovulation would likely have occurred around September 30 to October 1. Since you had unprotected sex on October 6 and 15, it is within the window where fertilization could occur if you ovulated around that time.
The symptoms you are experiencing, such as breast tenderness, can be an early sign of pregnancy, but they can also be attributed to other factors, including hormonal changes related to your menstrual cycle. The best way to confirm whether you are pregnant is to take a home pregnancy test. These tests are designed to detect the hormone hCG (human chorionic gonadotropin), which is produced shortly after a fertilized egg attaches to the uterine lining.
If you take a home pregnancy test and it shows a positive result, it is advisable to schedule an appointment with your healthcare provider for further evaluation and to discuss your options moving forward. If the test is negative but your period still does not arrive, you may want to retest in a few days or consult your doctor, as there could be other reasons for a missed period, such as stress, changes in weight, or hormonal imbalances.

In summary, based on your menstrual history and the timing of your unprotected sexual encounters, there is a possibility of pregnancy. Taking a home pregnancy test will provide you with the most immediate answer, and if you have any further concerns or questions, don't hesitate to reach out to your healthcare provider for personalized advice and support.
