Is a delayed menstrual period a sign of pregnancy?
My last menstrual period started on January 14, and my cycle usually lasts about 28 to 32 days.
However, I had intercourse with my boyfriend on January 25, during which we used a condom that did not break.
I also took a shower afterward, but my period still hasn't arrived as of today (February 17).
I calculated my fertile window online, which was from January 25 to January 31.
Should I be concerned that I might be pregnant since my period is late? If I take a pregnancy test now, will it show accurate results? I heard that the cycle is calculated from the first day of the last period, and since today marks 36 days without my period, I'm worried.
What should I do, doctor? I'm really anxious about the possibility of being pregnant.

When it comes to missed periods and the possibility of pregnancy, there are several factors to consider. Based on your description, your last menstrual period (LMP) was on January 14, and you had unprotected sexual intercourse on January 25. Given your menstrual cycle typically ranges from 28 to 32 days, it is understandable that you are concerned about the possibility of being pregnant, especially since your period has not arrived by February 17, which would make it 36 days since your last period.
Firstly, it is important to understand that a missed period can be one of the earliest signs of pregnancy, but it is not the only reason for a delayed menstrual cycle. Stress, hormonal imbalances, changes in weight, and various medical conditions can also lead to missed or delayed periods. Since you had protected intercourse, the likelihood of pregnancy is lower, especially if the condom did not break. However, no contraceptive method is 100% effective, and there is always a small risk of pregnancy with any sexual activity.
To determine if you are pregnant, the most reliable method is to take a home pregnancy test (HPT). These tests are designed to detect the hormone human chorionic gonadotropin (hCG) in your urine, which is produced shortly after a fertilized egg attaches to the uterine lining. Most home pregnancy tests are accurate when taken after a missed period, so given that you are now 36 days past your last period, you should be able to get a reliable result. If you take the test and it shows a positive result, it is advisable to schedule an appointment with your healthcare provider for further evaluation and confirmation through a blood test or ultrasound.
If the test is negative and your period still does not arrive, it is recommended to consult with a healthcare professional. They can help determine the underlying cause of your missed period and discuss any necessary evaluations or treatments. It is also important to consider that if you are experiencing any unusual symptoms such as severe abdominal pain, heavy bleeding, or other concerning signs, you should seek medical attention promptly.
In summary, while a missed period can indicate pregnancy, it is not definitive proof. Given your circumstances, taking a home pregnancy test is the best next step. If you have further concerns or if the test results are inconclusive, reaching out to a healthcare provider will provide you with the guidance and support you need. Remember, it is always better to seek professional advice when in doubt about your reproductive health.
