when can you take a early response pregnancy test

so I've seen some post on here where some women have taken a "first response" pregnancy test 8 days after ovulation and already got a positive reading (Congrats btw), I have a "6 days sooner first response" test and I'm 6 days away from my missed period. could i go ahead and test and get an accurate reading? I'm dying in suspense and I really don't want to wait one more day!
