I've been getting ridiculously faint positives since Christmas <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> on strip tests (that the camera couldnt pick up) and on one other cheap test. The strip test and clear blue were taking with the same FMU. I really don't rate testing early with these sticks half the time they only show positives after periods! 

Just wanted to post to give hope to any ladies thinking they are imagining positives on a strip test!
