hCG in a normal pregnancy doubles at a rate of every 48-72 hours. So you could take a pregnancy test in 3 days and it should show a better positive.
ok thanx about how long from now should i take another one
It's possible it could be early pregnancy. Retest (make sure to use a pink dye test) and use first morning urine. Make sure to also read the test in the time frame it gives--usually no longer than 10 minutes--and if it is still giving you a faint positive make an appointment with your doctor and request they check your hCG levels.
i took one a couple days ago and it was a ark line with a very faint line
Have you taken a pregnancy test at all?
