It can mean a lot of things, but keep this in mind - pregnancy tests are not 100% accurate - there is actually a fairly large margin of error on them.
Yes. Home pregnancy tests only read up to a certain amount of hCG or the pregnancy hormone. Anything above that number would read negative.

zero.
Most home pregnancy tests should be accurate from around 2 weeks after ovulation (coinciding with the time your period is due). If it shows negative at this point and you still miss your period, wait another week and retest. Pregnancy tests test for a hormone called HCG which basically doubles every day in early pregnancy, so after around 3 weeks of negative testing, you are probably not pregnant. If in doubt go to the doctor and get a blood test which will prove for definite eitherway.
It is always best to see a doctor because pregnancy tests are not always 100% accurate. If you think you may be pregnant, consult a physician. There are also free pregnancy clinics where I live in Louisiana, check the yellow pages for free pregnancy help or something similar.
