Normal variation: There is some normal variation in cycle length and that could be all it is. But, if you have been having unprotected intercourse, you could be pregnant. Do a pregnancy test and, if it is negative and your period still hasn't started, repeat it in 3-5 days to be sure. Now is also a good time to get in and start a reliable method of contraception if you aren't trying to conceive. Hope this helps.
