thanks i went to the doctor and the test results were normal and im not sexually active
are you sexually active? You are not that late yet but if you are worried you could always run a pregnancy test. A late period is not that uncommon unless you have reason to think u might be pregnant and even then, it is not time to worry yet. Give it another week but it sounds like your body is trying to gear up into having the event. If nothing in a week or so, do a pregnancy test, if that is negative, relax it could be simply stress keeping it at bay.
