Most likely you are NOT PREGNANT. Even for couples who have full-on sex during the right days of the month only have about a 25% chance of getting pregnant. IF any of the sperm got inside of you it all depends on if you were about to ovulate (drop the egg) within the next couple days and there is really no way of telling that unless you chart you basal body temperature and check your cervical mucus daily.
There would be a slight possibility but sperm do not live long when they are not in the right environment. Try not to stress too much about it as I think your chances are extremely extremely low. Take a test if you are late but I really don't think you will need to.
even though it is possible, it is highly unlikely.
As strange as this sounds...yes, you could become pregnant if your vagina touched the semen. Any time semen touches the vagina, even the outside, pregnancy is a possibility because vaginal fluid is created specifically to guide semen up through the cervix into the uterus..and determined sperm can make it from the vaginal opening.
