Menstrual delay


Hello, doctor! My boyfriend and I had sexual intercourse on May 8.
We had external rubbing without a condom, but I used a condom during penetration.
After that, I took a pregnancy test on May 20, which was negative, and I got my period from May 22 to May 27.
However, my period for June has not arrived yet, and it is now July 6.
I would like to know if there is a possibility of pregnancy.
Thank you, doctor.

Wishing you good health.

Understanding delayed menstruation and the possibility of pregnancy can be complex, especially when considering various factors such as timing of sexual activity, contraceptive methods, and individual menstrual cycles. Based on the details you've provided, let's break down the situation.

You mentioned that you had sexual intercourse on May 8, using a condom during penetration but engaging in external contact without protection. Following this, you took a pregnancy test on May 20, which was negative, and then experienced your menstrual period from May 22 to May 27. This indicates that you likely were not pregnant at that time since a menstrual period typically signifies that ovulation did not result in fertilization.

However, the absence of your June period, which you expected by July 6, raises the question of whether you could be pregnant. Here are several considerations:
1. Timing of Ovulation: The menstrual cycle can vary significantly among individuals. If your cycle is irregular, it may lead to a delayed period. Ovulation typically occurs about 14 days before your next expected period, but this can vary. If you ovulated later than usual, it could explain the delay.

2. Pregnancy Testing: The negative pregnancy test on May 20 suggests that you were not pregnant at that time. However, if you ovulated later in your cycle, it is possible to conceive from intercourse that occurred earlier in the month. If you suspect you might be pregnant, it would be advisable to take another pregnancy test, ideally a week after your missed period for more accurate results.

3. Contraceptive Efficacy: While condoms are generally effective at preventing pregnancy, no method is 100% foolproof. The risk of pregnancy exists even with condom use, particularly if there was any slippage or breakage during intercourse, or if pre-ejaculate fluid came into contact with the vaginal area.

4. Other Factors: Stress, hormonal imbalances, changes in weight, illness, or other lifestyle factors can also affect your menstrual cycle. If you have experienced significant changes in your life or health, these could contribute to a delayed period.

5. Next Steps: If your period does not arrive soon, consider taking another home pregnancy test. If it remains negative and your period does not start, it would be wise to consult 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 menstruation.

In summary, while the initial signs suggest that you were not pregnant following your sexual encounter in May, the delayed period in June warrants further investigation. Taking another pregnancy test and consulting with a healthcare professional can provide clarity and ensure that any underlying issues are addressed. Remember, maintaining open communication with your healthcare provider about your menstrual health is crucial for your overall well-being.
