Faint line still

So I got a faint line positive 8/8. My original start daye was 8/5, but when I input my positve ovulation test 7/27, one of my apps changed my start date to 8/11. I've since tested every day since 8/8. The line I am getting still is faint and not as dark as it was 2 days ago. I've had one chemical pregnancy before and hoping that the faint line is no indication of that. Just wanted some feedback. I am unable to get into the doctor until 9/1 so blood work hcg levels are not an option unless someone knows how to get that done elsewhere!
