Pregnancy test before missed period


Has anyone used the first response early detection pregnancy test 4 days before their expected period (using morning urine) and was the result accurate? I’m not due for my period for 5 days still, but tomorrow would be 4 days… just not sure? Pictured is my cycle chart and the pregnancy test I’ve bought. Have you used this test 4 days before your period was due and was it accurate?
