The answer appears to be: It depends....on the test, and the level of pregnancy hormone in your body.
On the frequently asked questions page of the clear blue easy pregnancy test (first test that popped to mind), they have two types of tests. One that can tell you pretty much the day of your expected period. The other that can detect up to 5 days before your expected period. Search "clearblue easy faq" for actual page.

about 5 weeks
It depends on your period. Usually pregnancy tests pick up a pregnancy by 4-5 weeks. So if you didn't get a positive last week, you are probably between 4-7 weeks :)
What was the first day of your period? That is more important as that is when pregnancy is counted from.
Depending on how sensitive the home pregnancy test is, some claim to detect pregnancy as early as 7-14 days after conception. The test measures the hormone hCG, which is released by the body after conception. For best results, take the test with the first morning urination, or wait several hours since the last time you've urinated. Drinking large amounts of water or frequent urination can create inaccurate results. Good luck!
The absolute value of a number means how far a certain number is from zero on a number line. so a negative is always positive because it is not possible to be a negative amount away from zero

You should wait at least 14 days after having sex for the best result
The only way to determine if youare pregnant, and how far along you- are is to have a blood test, or to have an ultrasound to confirm the pregnancy.
