Trying not to keep my hopes up please give some insight!!

Okay so I'm 9dpo today and I was planning on taking my first hpt tomorrow morning but unfortunately I have a good feeling and couldn't refrain. Naturally I took the test and of course thought it was negative BUT I looked real real careful and I'm SURE I saw a slight slight line. Then I thought I was having line eyes but I kept seeing it but it wouldn't show up on a picture even after tweaking. Being determined as I am I had to make sure there wasn't there so I took a flashlight and put it under the test and the slightest yet THERE line was there. I have done that many times in the past with others and NEVER on a negative test have I seen ANYTHING. I want to know if anyone else has had the same thing and took a second test for FMU and have a visible line?? I'm really hoping for a positive this will be me and my husband's rainbow baby and if it's real fingers cross it sticks!!
