Two faint lines, negitive digital???

Lauren
So I took two pregnancy test...first response pink dye tests and they both have faint lines on them. Unmistakable pink lines. But for some reason my digital test said no. I might not be for enough along to get a reading. I'm a day late on AF. My body definitely feels different. I don't feel how I normally do when my period is going to show up. Should I still go to my doctor and see if I should get blood work or take one of their pregnacy tests?? I am so excited to be having a baby...I don't want this to end up a negative. It will probably unmotivated me.
