Miscarriage help please

A
I had a miscarriage last week at 6 weeks. The bleeding has stopped now but I'm still getting positive tests. I have spoken to the early pregnancy unit who have made me an appointment for a weeks time for a scan if I am still getting a positive hpt result. I have been quite strong until now but I am struggling today and could really do with some support right now. How long did anyone that has had a miscarriage get a positive hpt result for?
