Possibly still pregnant?

So I had sex every day, most of the time twice ๐Ÿ˜“๐Ÿ˜“๐Ÿ˜“ starting 2 days before my fertile window and every day since then (minus 1 day cause I was over it haha) and I've been having small symptoms of pregnancy. Glow said I could test yesterday so I did, at around 7:30 pm and it was negative :(ย 
I'm due on the 19th (Friday) and I read that someone else done a test yesterday which was negative but they were gunna wait until Saturday to test again, do you think there's still a chance or would the result be pretty accurate this close to my period???ย
