Sometimes your period is just whacked up for a month or so. You may not figure out the reason. Mine was 3 weeks late recently and I was cramping the entire time. Any of the above things could cause it or any number of others which can throw hormones off balance. Take a test every few days...eventually you will get a positive result or AF will show her face. It is also totally normal for a woman to SKIP a period once a year or so without being pregnant. If you miss more than one and still have a negative test, you really need to see a doctor to rule out any sort of hormonal or physical abnormality. Good luck.
