What is the likelihood of getting pregnant this way?

On January 10th, I had intercourse with my girlfriend.
Since she didn't want to get pregnant, I used a condom.
After finishing, I removed the condom and wiped my genital area with tissue.
About half an hour later, we had intercourse again, but this time I moved a few times before realizing I wasn't wearing a condom, and I quickly pulled out.
What are the chances of her getting pregnant in this situation?

More Info

The chance of pregnancy after unprotected intercourse can vary significantly based on several factors, including the timing of the menstrual cycle, the fertility of both partners, and the presence of sperm in the vaginal canal. In your case, since you had unprotected intercourse after initially using a condom, there are a few key points to consider.

1. Timing in the Menstrual Cycle: If your girlfriend has a regular menstrual cycle, ovulation typically occurs around 14 days before the start of her next period. If the unprotected intercourse happened during her fertile window (which is usually about five days before ovulation and the day of ovulation itself), the chances of pregnancy increase significantly. Conversely, if it occurred outside of this window, the likelihood is lower.

2. Sperm Viability: Sperm can live inside the female reproductive tract for up to five days. If the unprotected intercourse occurred close to her ovulation period, there is a higher chance that viable sperm could fertilize an egg.

3. Withdrawal Method: You mentioned that you removed the condom and wiped down before the second intercourse. It's important to note that pre-ejaculate fluid (pre-cum) can contain sperm, and if any sperm were present, there is a risk of pregnancy even if ejaculation did not occur inside the vagina.

4. Statistics: Generally, the average chance of pregnancy from unprotected intercourse is about 20-30% per cycle, depending on the factors mentioned above. If intercourse occurs during the fertile window, this percentage can rise to as high as 30-40%.

5. Emergency Contraception: If your girlfriend is concerned about the possibility of pregnancy, she may consider taking emergency contraception (EC) within 72-120 hours after unprotected intercourse. EC is most effective the sooner it is taken and can significantly reduce the risk of pregnancy.

6. Pregnancy Testing: If your girlfriend misses her period or experiences any symptoms of pregnancy (such as nausea, breast tenderness, or fatigue), she should take a home pregnancy test or consult a healthcare provider for a more accurate assessment.

In summary, while there is a possibility of pregnancy after unprotected intercourse, the actual risk depends on various factors, including the timing of the cycle and the presence of sperm. If there are concerns about potential pregnancy, it is advisable to discuss options with a healthcare professional and consider emergency contraception if appropriate.
