Pregnancy probability


On October 8th, during sexual intercourse on the 7th day of menstruation, there was still a little bleeding.
After using a condom for the first time and ejaculating, I immediately changed to another condom.
I wiped my hands with a wet tissue but did not clean my penis before putting on the second condom, and I did not ejaculate the second time.
Is there a risk of pregnancy?

Hello, based on your description, there is a possibility of pregnancy, as the failure rate of correctly using condoms is still around 5%.
Generally, it is not recommended to rely solely on condoms for contraception.
I suggest that if your period is a week late, you should take a urine test to check for pregnancy.
Thank you! Wishing you safety and health.

More Info


When it comes to understanding the chances of pregnancy after unprotected intercourse, several factors come into play. Based on your description, you had sexual intercourse on the 7th day of your menstrual cycle, which is typically considered a low-fertility period for most women. However, it is essential to understand that sperm can survive in the female reproductive tract for up to five days, and ovulation can vary from cycle to cycle.

In your case, since you mentioned that you had a slight bleeding episode, it is important to clarify whether this was a normal menstrual flow or something else. If it was indeed your menstrual period, the likelihood of pregnancy from intercourse during that time is generally low. However, if you were close to ovulation, which can occur around the midpoint of your cycle (typically 14 days before your next period), there is still a possibility of pregnancy.

Regarding the use of condoms, you mentioned that you switched condoms after ejaculation and did not clean your hands thoroughly before putting on the second condom. While this may introduce a slight risk of sperm transfer, the risk remains relatively low, especially if the second condom was applied correctly and there was no direct contact with ejaculate.

To assess your chances of pregnancy accurately, consider the following:
1. Timing of Intercourse: If you had intercourse during your menstrual period, the chances of pregnancy are lower. However, if you have irregular cycles or if ovulation occurred earlier than expected, there could still be a risk.

2. Sperm Viability: Sperm can live in the female reproductive tract for several days. If you ovulated shortly after your intercourse, there is a chance of conception.

3. Contraceptive Failure: Although you used condoms, no contraceptive method is 100% effective. If there was any breakage or slippage, the risk of pregnancy increases.

4. Menstrual Cycle Variability: Every woman's cycle is unique. If you have a longer or shorter cycle than the average 28 days, this could affect your ovulation timing and, consequently, your chances of pregnancy.

If you are concerned about the possibility of being pregnant, the best course of action is to wait until your next expected period and take a home pregnancy test. These tests are most accurate when taken after a missed period. If you experience any unusual symptoms or have further concerns, consulting a healthcare provider would be advisable.

In summary, while the chances of pregnancy from the scenario you described appear to be low, it is not impossible. Factors such as the timing of ovulation, the viability of sperm, and the effectiveness of the contraceptive methods used all play a role in determining your pregnancy risk. If you have any doubts or experience any unusual symptoms, seeking medical advice is always a prudent step.
