Different types of FRT (First Response Test)

Ok so there are 3 types of FRT one is digital and comes in a white foil package, second is early detection which comes in the dark pink foil package, then lastly comes the rapid result in a teal foil package. My question is has anyone gotten an early BFP with the rapid result? Those are supposedly only accurate AFTER you’ve missed your period, but seems how that was the only FRT the store closest to me had I had to get it. I’m 3 days from my “period” and I wondering the accuracy of these tests before the missed period.
