Am i having a chemical/miscarriage ?

Hi tested around 6-7dpo with positive then was getting faint barely visible lines after so when period was due on thursday, took test which had thick pink positive line - in pics- now day after friday. Was barely visible but still there and has been same since , i whole heartedly think i am having another chemical pregnancy am contacting my gp monday sure i will be told to wait and test in 2 weeks but has this ever happened to any one and had a positive outcome :(
