False Postives??

I took a pregnancy test this morning (clear blue with week indicator) and it said pregnant 1-2 weeks. Obviously I went out and bought a bunch more. I took 3 more- 2 digital and one with the lines. The two digitals said negative this time and the line test could have faintly had 2 lines?? (am I imagining things now?!).  Not sure what to think... Is is more likely to believe I have some false negatives or a false positive??
