Advice please. Possible miscarriage

Hi ladies. I'm 5 weeks 5 days. And I started bleeding 2 days ago and stopped yesterday morning. No cramps no clots. Pink blood. It did turn a bit red though. I've taken a test today and it's positive. I know hcg will still be in my body. But my question is, if I have miscarried will the pregnancy test line get lighter as the hcg leaves my body (as it gets darker when hcg levels double). Thank you ladies.
