Pregnancy Chances After Protected Intercourse and Pre-ejaculation

Probability of pregnancy

Approximately around the ovulation period, sexual intercourse occurred with a condom used throughout.
Afterward, a check was done to ensure the condom did not break.
However, prior to putting on the condom, there was some manual stimulation of the partner, which may have resulted in some pre-ejaculate fluid being transferred.
What is the likelihood of pregnancy in this scenario? Additionally, if fingers that had come into contact with the prostate were then inserted into the vagina, what is the likelihood of pregnancy? The last menstrual period was from January 5 to January 11, with a cycle length of about 31 days, and sexual intercourse occurred from January 23 to January 25 (with condoms used throughout).

Hello, the failure rate of using condoms as a contraceptive method is over 5%, which is less reliable compared to other methods.
If sexual activity is frequent, it is not advisable to rely solely on condoms.
Additionally, as long as there are active sperm in the vagina during the ovulation period, there is still a possibility of pregnancy regardless of the method used.
It is recommended to take appropriate contraceptive measures, and if necessary, consult a physician for evaluation.
If your menstrual period is more than a week late, it is important to check for pregnancy.
Thank you! Wishing you safety and health.

More Info

When considering the chances of pregnancy after protected intercourse, especially during the ovulation period, it is essential to understand the mechanics of sperm transfer and the effectiveness of condoms as a contraceptive method.
In your situation, you mentioned that you had sexual intercourse around your ovulation period while using condoms throughout. Condoms are generally effective in preventing pregnancy when used correctly, with a failure rate of about 2% with perfect use and around 15% with typical use. However, the effectiveness can be compromised if the condom breaks or if there is any transfer of sperm from pre-ejaculatory fluid (pre-cum).

Pre-ejaculatory fluid can contain sperm, although typically in lower concentrations than ejaculate. If you touched your boyfriend's penis and then inserted your fingers into your vagina, there is a potential risk of transferring sperm from that fluid, especially if there was any sperm present in the pre-ejaculatory fluid. However, the likelihood of pregnancy from this scenario is relatively low, particularly if the condom was used correctly and did not break.

Regarding your menstrual cycle, if your last period was from January 5 to January 11 and you had intercourse from January 23 to January 25, you were likely within your fertile window, which typically spans from about five days before ovulation to the day of ovulation itself. If you ovulate around the midpoint of your cycle (approximately day 14 for a 31-day cycle), the timing of your intercourse could align with your fertile window, increasing the chances of pregnancy if sperm were present.

To summarize, while there is a theoretical risk of pregnancy due to the transfer of sperm from pre-ejaculatory fluid, the actual risk remains low if the condom was used properly and did not fail. If you are concerned about the possibility of pregnancy, it is advisable to wait until your next expected period and, if it is late, consider taking a home pregnancy test for confirmation.
In addition, if you are actively trying to avoid pregnancy, it is essential to practice comprehensive contraception methods. This could include using condoms in conjunction with other forms of birth control, such as hormonal contraceptives, to enhance protection. If you have further concerns or experience any unusual symptoms, consulting with a healthcare provider can provide personalized guidance and reassurance.

Hello, on May 4th you should still be in the safe period, so the chances of pregnancy are low. However, pre-ejaculate fluid cannot guarantee the absence of sperm, so it is best to use preventive measures beforehand. Wishing you good health.
