Miscarriage confused

Tayler

So 4 days ago I went to the ER with heavy bleeding and cramping, they did an ultrasound and blood work and unfortunately I miscarried, now 4 days later thwy wanted to repeat my blood work to make sure my hcg has gone down, they said my hcg is back down to a 1, I have stopped bleeding and took a home test after the doctors and it’s still positive? How would it be positive if my hcg is only at a 1? So confused
