Confused! Please help!?

Girls, I have just done a clearblue digital pregnancy test as I couldn't wait until first wee in the morning and I got the book error... I think I tilted it too much... But then I got a pregnant reading too on the same test a couple of seconds later? Has anyone had this? I had a failed implantation last month and so not sure how late I am, I might be a week and a half late or I may be a few days late? I know I will have to retest tomorrow but just wanted to get your thoughts?!!! Xxx
