Confused

I posted a few days ago asking if anyone seen the vvvvf line in a test I took. Well today I decided to get a digital one and it said not pregnant. So I tried to come with terms with it but then decided I wonder what it looked like inside. When I took it a part you could clearly see the control line but also there is another faint 2nd line. Does this mean I'm pregnant and there just isn't enough hcg in my urine to have it say pregnant?? I have a Dr appointment tomorrow morning. Here's the pictures.
