Is there a risk of pregnancy in this situation?


Hello doctor, I had sexual intercourse with my boyfriend on April 22, but he pulled out after about three thrusts and there was no ejaculation inside.
It seems that my hymen was not broken.
My recent menstrual periods were on April 7 and March 9, with a typical cycle of 29 days.
What is the likelihood of becoming pregnant in this situation? Is it almost impossible?

Hello, the questioner: There is still a possibility of pregnancy even if ejaculation has not occurred during intercourse, as pre-ejaculatory fluid may contain sperm.
It is recommended to check for pregnancy if your period is more than a week late.
Thank you! Wishing you peace and health.

When it comes to understanding the risks of pregnancy after brief intercourse, it’s important to consider several factors, including the timing of the menstrual cycle, the nature of the sexual activity, and the effectiveness of any contraceptive methods used.

In your case, you mentioned that you had intercourse on April 22, with your last menstrual period starting on April 7. Given that you typically have a 29-day cycle, ovulation would likely occur around day 15 of your cycle, which would be approximately April 21. Since sperm can survive in the female reproductive tract for up to five days, there is a possibility that sperm from the intercourse on April 22 could still be viable if ovulation occurred around that time. However, since you indicated that there was no ejaculation inside the vagina, this significantly reduces the likelihood of pregnancy.

The risk of pregnancy from brief intercourse, especially if there was no ejaculation, is relatively low, but not zero. The pre-ejaculate fluid (pre-cum) can contain sperm, although the quantity is usually much lower than in ejaculate. If you are concerned about the possibility of pregnancy, it may be beneficial to take a home pregnancy test if your period is late or to consult with a healthcare provider for further guidance.

Additionally, it’s important to understand that the menstrual cycle can be affected by various factors, including stress, illness, and changes in routine, which can sometimes lead to irregularities in timing. If you find that your periods are consistently irregular or if you have any other concerns about your reproductive health, it would be wise to seek advice from a healthcare professional.

In terms of your question about the likelihood of pregnancy, while the chances are low given the circumstances you described, it is not impossible. If you are looking for more immediate reassurance, consider using emergency contraception if you are within the appropriate time frame, which is typically within 72 to 120 hours after unprotected intercourse, depending on the type of emergency contraceptive used.

In summary, while the risk of pregnancy from the brief intercourse you described is low, it is not entirely absent. Monitoring your menstrual cycle and being aware of any changes in your body can help you stay informed about your reproductive health. If you have further questions or concerns, don’t hesitate to reach out to a healthcare provider for personalized advice and support.
