Pregnancy tests??

So I got the 6 days before misse dperiod pink test the one that reads “pregnant” or “not pregnant” and decided to take one even though I’m days away from when I’m supposed to get my period I tested and it read “no” so my question is does this test only say “yes” when for sure pregnant cause I see faint lines all the time at start of pregnancy would it not predict that like the lines test do or is it the same? (I’m obviously just going to see if I miss my period before new test but wondering for future reference)
