Clearly, if a guy ejaculates in your vagina, the sperm will swim all the way up inside, and you can possibly be pregnant. When the sperm gets its way in the vagina, thousands of of small sperm will find the egg that females have. Only one sperm can make a female pregnant. You will know if your pregnant if your late on your period. Wait a week from now and see if your late, and if you are go take a pregnancy test. Don't stress.

this is only 100 percent if you DON'T wear a condom and have "safe" sex. that pregnancy is preventable. If you don't want to be pregnant, wear a condom. Good luck on everything.
