Best pregnancy test to use?

What is the best pregnancy test to use for early detection?? I’m 6 days away from my period and had unprotected sex on the 13th and 17th but I’m guessing that’s too soon to tell.

A cheap pink dye. Early detection. Think most are 6 day before

I like the first response brand they have always been right. I took a clear blue digital once and it said error so I bought a first response and it was positive
