Since you are only 5 days late, it may be that the test you are using is not sensitive enough. Home test are not 100% accurate. Even those that do get a positive reading, are not always pregnant. You can either wait a 72 hours. hCG (pregnancy hormone) rises generally every 72 hours. So wait that amount of time and re-test again if you don't start. Make sure to follow the directions exactly and use your first morning urine. If you get another Neg- then I would actually confirm this with your doctor via blood testing just to make sure. Sometimes when woman are trying to get pregnant, they can actually delay menstruation and start to have symptoms of pregnancy because they are actually want to be pregnant. So try to relax over the weekend. Try again in a couple of days and see how it goes.
