answer:There is a chance you could be pregnant. There is almost always a small chance. Did you use protection? Do you have any reason to believe you’re pregnant besides just being worried about it? If you don’t get your period, then take a pregnancy test. Try not to think about it until then. Also, there are probably better forums than this for that type of question. I’m not being rude, but you might try finding a women’s health type place to get some better and more scientific answers. I know livejournal has a community specifically called, “Am I pregnant?” Good luck.
