In the vaginal environment, sperm can survive for approximately 4 hours, while in the uterine cavity, they can survive for about 10 hours.
In the cervical mucus, sperm can survive for around 72 hours.
The speed of sperm is approximately 20 centimeters per hour, but if they are at the vaginal opening without a fluid environment, it is usually unlikely for them to enter the vagina unless manually assisted.
Therefore, based on your situation, the likelihood of pregnancy is low.

More Info

When it comes to understanding the risks of pregnancy after unprotected anal intercourse, there are several important factors to consider. First and foremost, it's crucial to clarify that while anal intercourse itself does not directly lead to pregnancy, there are scenarios where the risk of pregnancy can arise, particularly if semen comes into contact with the vaginal area.

In your situation, since the condom broke during anal intercourse and there was a possibility of semen coming into contact with the vaginal opening, there is a potential risk of pregnancy. Sperm can survive outside the body for a short period, and if it was deposited near the vaginal entrance, there is a chance that some sperm could migrate into the vagina, leading to potential fertilization if ovulation is occurring.

The likelihood of pregnancy in this scenario is generally considered low, especially if the semen did not directly enter the vagina. However, it is not zero. The risk is influenced by several factors, including the timing of your menstrual cycle. If you are close to ovulation, the chances of becoming pregnant increase, as this is when the egg is available for fertilization.

Additionally, the presence of blood in the discharge you noticed could be a sign of irritation or minor trauma, especially since you mentioned experiencing pain during the initial penetration. It's important to monitor any unusual symptoms, such as persistent pain, unusual discharge, or changes in your menstrual cycle, and consult a healthcare professional if you have concerns.

For future reference, if you are engaging in sexual activities that involve potential risks of pregnancy or sexually transmitted infections (STIs), it is advisable to use protection consistently and correctly. Condoms are effective in reducing the risk of both pregnancy and STIs when used properly. If you find that a condom breaks, consider emergency contraception options if you are concerned about pregnancy, and consult with a healthcare provider for personalized advice.

In summary, while the risk of pregnancy from the scenario you described is relatively low, it is not negligible. If you have further concerns about your risk of pregnancy or any symptoms you may be experiencing, it is best to consult with a healthcare professional who can provide guidance based on your specific situation.
