Pregnancy probability
Hello doctor, on May 27th, I had unprotected vaginal intercourse with my boyfriend, but he withdrew in less than 20 seconds.
I did not feel any fluid being released during the encounter.
However, the calendar app indicated that it was my ovulation day, which has a high chance of conception.
In the following days, I experienced slight breast tenderness, and yesterday I had lower back pain after walking a lot.
Today, I noticed a small amount of bleeding (the app indicates my period is due in four days).
What is the likelihood of pregnancy in this situation?

Hello, the chances of pregnancy should be low.
Let's wait another week to see if your period arrives.
If it does, there is no issue.
If it doesn't, I recommend seeing a gynecologist.
Wishing you good health.

More Info
When considering the chances of pregnancy after unprotected intercourse, especially during the ovulation period, it's essential to understand a few key factors. In your case, you had unprotected intercourse on May 27, which coincided with your ovulation day according to your tracking app. This timing is crucial because the likelihood of conception is highest when intercourse occurs within the fertile window, which typically spans the five days leading up to ovulation and the day of ovulation itself.
The fact that you mentioned the intercourse lasted less than 20 seconds and that you did not feel any fluid release may provide some reassurance, but it is important to note that pre-ejaculatory fluid (pre-cum) can still contain sperm. Even if there was no noticeable ejaculation, the presence of sperm in pre-ejaculatory fluid can lead to pregnancy, particularly if it occurs during your fertile window.
Regarding your symptoms, breast tenderness and lower back pain can be early signs of pregnancy, but they can also be attributed to hormonal changes associated with your menstrual cycle. The slight bleeding you experienced could be implantation bleeding, which occurs when a fertilized egg attaches to the uterine lining. However, it could also be a sign that your period is approaching, especially since your app indicates that your menstrual cycle is due in four days.
To assess your chances of pregnancy more accurately, consider the following:
1. Timing of Intercourse: Since you had intercourse on your ovulation day, the chances of pregnancy are relatively high, especially if sperm were present.
2. Symptoms: While breast tenderness and back pain can indicate pregnancy, they are not definitive signs. The bleeding you experienced could be a sign of your period starting or implantation bleeding.
3. Pregnancy Testing: The most reliable way to determine if you are pregnant is to take a home pregnancy test. These tests are most accurate when taken after a missed period, so if your period does not arrive as expected, consider testing a few days after your expected date.
4. Consulting a Healthcare Provider: If you have concerns about your symptoms or the possibility of pregnancy, it may be beneficial to consult a healthcare provider. They can offer guidance, perform tests, and provide support based on your individual situation.
In summary, while there is a possibility of pregnancy given the timing of your intercourse, the only way to confirm is through a pregnancy test. If you have any further questions or concerns, don't hesitate to reach out to a healthcare professional for personalized advice and support.
