Hcg levels and faint lines

Hannah

Has anyone anyone had continually faint positive and still had a healthy pregnancy? I tested at 11dpo- now which I am 15dpo today and I’m still just getting a faint line it has gotten a little darker but really not much of a difference. Is this normal? I tested positive on a clear blue digital but I’m worried my HCG levels aren’t rising like they should. According to my app I’m only 4 weeks and 1 day today, I tested today and still got a faint line on a pregnancy test.
