The probability of pregnancy from brief unprotected intercourse without ejaculation?

Hello doctor, my menstrual cycles for the past few months have been from January 16-21, February 12-17, and March 11-18.
In April, due to the third dose of the vaccine, I experienced frequent bleeding, but I estimate my period was from April 7-13.
I had sexual intercourse on April 22-24, during which I used condoms on April 22-23 and withdrew before ejaculation, meaning there was no internal ejaculation at all! However, on the night of April 24, I initially had a few thrusts without a condom before putting one on and re-entering, and again, there was no internal ejaculation! I checked the condom afterward, and it did not break! I would like to know what the chances of pregnancy are in this situation.
Also, I would like to ask if April 22-24 was my ovulation period?

Hello, the questioner: Due to your recent irregular menstrual cycle, it is difficult to predict both your ovulation period and the onset of your menstruation.
The failure rate of using condoms as a contraceptive method is over 5%, which makes it less reliable compared to other methods.
Generally, it is not recommended to rely solely on condoms for contraception.
Therefore, if your menstrual period is more than a week late, it is advisable to check for pregnancy.
Thank you! Wishing you peace and health.

More Info

When it comes to assessing the risk of pregnancy after unprotected intercourse, several factors must be considered, including the timing of the menstrual cycle, the use of contraceptives, and the nature of the sexual activity. Based on the information you provided, let's break down the situation.

Understanding Your Menstrual Cycle
Your menstrual cycle appears to be relatively regular, with periods occurring approximately every 28 to 31 days. You mentioned your last menstrual period started on April 7 and lasted until April 13. Ovulation typically occurs about 14 days before the start of your next period. If we assume your cycle remains consistent, ovulation would likely occur around April 21, which places your fertile window from approximately April 18 to April 23.

Sexual Activity and Contraceptive Use
You indicated that you engaged in sexual activity on April 22 and 23 while using condoms, and you were careful to withdraw before ejaculation. This significantly reduces the risk of pregnancy, as long as the condom did not break or slip off during intercourse. On April 24, you mentioned having unprotected intercourse initially before using a condom. This is where the risk of pregnancy could increase, especially if ovulation occurred shortly after.

Assessing Pregnancy Risk
1. Condom Use: Since you used condoms correctly on the days leading up to your ovulation, the risk of pregnancy from those encounters is low. Condoms are highly effective when used properly, and you confirmed that they did not break.

2. Unprotected Intercourse: The unprotected intercourse on April 24 poses a higher risk, particularly if it occurred close to your ovulation window. However, since you did not ejaculate inside, the risk is still lower than if ejaculation had occurred.

3. Timing of Ovulation: Given that ovulation likely occurred around April 21, the days immediately following (April 22-24) are within the fertile window. Thus, any unprotected intercourse during this time carries a higher risk of pregnancy.

Conclusion and Recommendations
Based on your description, the likelihood of pregnancy is not negligible, particularly due to the unprotected intercourse on April 24. However, since you were careful with condom use on the preceding days, the overall risk remains lower than it would be without any contraceptive measures.

If you are concerned about the possibility of pregnancy, consider the following steps:
- Wait for Your Next Period: If your period is late, take a home pregnancy test to confirm whether or not you are pregnant. These tests are most accurate when taken after a missed period.

- Consult a Healthcare Provider: If you have any unusual symptoms or concerns, such as changes in your menstrual cycle, abdominal pain, or unusual discharge, consult a healthcare provider for further evaluation.

- Consider Emergency Contraception: If you are worried about the risk of pregnancy from the unprotected intercourse on April 24, you might consider taking emergency contraception (like Plan B) if it is within the recommended time frame (typically within 72 hours after unprotected intercourse).

Final Thoughts
Understanding your menstrual cycle and the timing of ovulation is crucial in assessing pregnancy risk. While the use of condoms significantly reduces the risk of pregnancy, any unprotected intercourse during the fertile window should be taken seriously. Always consult with a healthcare professional for personalized advice and to address any concerns you may have regarding sexual health and contraception.
