Help!!! So confused and anxious!

I took two digital test yesterday and they came out positive! I took a regular blue dye test today and it is a very faint positive! Are my levels dropping or am I over thinking this? I had a MC three months ago and when I took a normal blue dye test then the positive was dark just a couple days after missed period. What can this mean? I am freaking out because the line is not as dark. Could it be that I drank a bottle of water before taking the test?

Please help!
