How long did you carry on getting positive tests

So I was 10 weeks pregnant and last Tuesday started bleeding been very heavy all week lots of clots confirmed last Wednesday that baby was measuring 6 weeks and no heartbeat I go tomorrow to confirm a week on and to see if everything has come away naturally

Anyway I know I’m crazy but that little 1% is hoping it’s all wrong and they will see a heartbeat so I took a pregnancy test today hoping to see the line get lighter but it’s still really strong how long was it before you started to see the line disappear?
