If the condom slipped off during intercourse without your knowledge and you continued thrusting (without ejaculation), the risk of pregnancy is relatively high.
Essentially, if the condom comes off, it is similar to not using any protection at all.

More Info

When a condom slips off during intercourse, especially during the fertile window of a woman's menstrual cycle, there is a potential risk of pregnancy. The likelihood of conception in this scenario can vary based on several factors, including the timing of the woman's ovulation, the presence of sperm in the vaginal canal, and the overall fertility of both partners.

Firstly, it's important to understand the menstrual cycle. The average cycle lasts about 28 days, with ovulation typically occurring around day 14. However, cycles can vary significantly among women, and even for the same woman from month to month. The fertile window is generally considered to be the five days leading up to ovulation and the day of ovulation itself. If intercourse occurs during this time, the chances of sperm meeting an egg are higher.

In your case, if the condom slipped off during the fertile window and there was penetration without ejaculation, there is still a risk of pregnancy. Pre-ejaculate fluid, which can be released before ejaculation, may contain sperm. Although the concentration of sperm in pre-ejaculate is usually lower than in ejaculate, it is still possible for it to lead to pregnancy.

The risk of pregnancy in this situation can be influenced by several factors:
1. Timing: If the incident occurred close to ovulation, the risk of pregnancy is higher. If it happened just after ovulation, the risk decreases significantly as the egg is only viable for about 12-24 hours after ovulation.

2. Sperm Viability: Sperm can live inside a woman's reproductive tract for up to five days, so if sperm were present during the time of the condom slipping off, there is a possibility of fertilization if ovulation occurs within that timeframe.

3. Fertility Factors: The fertility of both partners plays a role. If the woman has regular ovulatory cycles and the male partner has a healthy sperm count, the chances of conception increase.

If you are concerned about the possibility of pregnancy following this incident, there are a few steps you can take:
- Emergency Contraception: If the incident occurred within the last 72-120 hours, emergency contraception (like Plan B or Ella) can be taken to reduce the risk of pregnancy. It is most effective the sooner it is taken after unprotected intercourse.

- Pregnancy Testing: If your partner misses her period or experiences unusual symptoms, a home pregnancy test can be taken about a week after the missed period for accurate results.

- Consult a Healthcare Provider: If there are ongoing concerns about contraceptive methods or the risk of pregnancy, it may be beneficial to consult a healthcare provider. They can provide personalized advice and discuss more reliable contraceptive options.

In conclusion, while the risk of pregnancy when a condom slips off during intercourse is not negligible, it is influenced by various factors. Understanding the timing of ovulation and the nature of sperm can help assess the risk. If there are concerns about potential pregnancy, taking appropriate actions such as using emergency contraception and consulting a healthcare provider is advisable.
