If there's a possibility of miscarriage how long will a pregnancy test show positive?

In brief: Several weeks

A pregnancy test will be positive as long as there is tissue in the uterus releasing hcg, or "pregnancy hormone".
A growing pregnancy will always make hcg. A miscarrying pregnancy will still have a positive urine test, but may have a decreasing trend on a quantitative (numeric) blood test for hcg. Hcg will remain present for several weeks after a complete miscarriage.
