Possible: This could just be some of the normal variation in cycle length but any time you have unprotected intercourse and your period is late you could be pregnant. If you conceived on the 13th the pregnancy test could be negative simply because it is too early. If your period still hasn't started, repeat the test in 3-5 days to be sure. Hope this helps.
