Hello, if there has been no sexual contact since your last menstrual period, then you should not be pregnant.
However, if there has been sexual contact and your period is late, it is recommended to take a pregnancy test.
Thank you! Wishing you peace and health, Dr.

When considering the possibility of pregnancy after engaging in sexual intercourse, especially when using condoms, it is essential to understand the factors that contribute to delayed periods and the effectiveness of contraceptive methods. Based on the information provided, you had protected sex with your boyfriend in mid-June, and you experienced a menstrual period shortly after. However, your period is now delayed this month, leading to concerns about potential pregnancy.

First and foremost, condoms are a reliable form of contraception when used correctly. They have a failure rate of about 2% with perfect use and around 15% with typical use, which accounts for human error. If you used the condom properly throughout the sexual encounter, the risk of pregnancy is significantly reduced. However, it is important to note that no contraceptive method is 100% effective, and there is always a small risk of pregnancy, especially if the condom breaks or slips off during intercourse.

Regarding your delayed period, several factors could contribute to this situation. Stress is a common factor that can affect the menstrual cycle. You mentioned that you were under pressure, which could lead to hormonal fluctuations that may delay your period. Other factors include changes in weight, exercise habits, and underlying health conditions such as polycystic ovary syndrome (PCOS) or thyroid disorders.

If you have taken a pregnancy test and it was negative, it is a good indication that you are not pregnant, especially if taken after a missed period. However, if your period is significantly delayed (more than a week), it is advisable to take another pregnancy test for confirmation. Home pregnancy tests are most accurate when taken after a missed period, as they measure the hormone hCG, which is produced during pregnancy.

If your period continues to be delayed and you are experiencing symptoms such as breast tenderness or other changes, it may be beneficial to consult with a healthcare provider. They can perform a blood test for pregnancy, which is more sensitive than home tests, and evaluate other potential causes for your delayed period.

In summary, while the risk of pregnancy exists, the use of condoms significantly reduces that risk. If your period is delayed, consider factors such as stress and hormonal changes, and take a pregnancy test if you haven't already. If you remain concerned or if your period does not arrive soon, seeking medical advice is a prudent step to ensure your health and peace of mind.
