Hello. I am currently on day 7. Tested positive on day 0, faint line which got very dark by the next day. I tested on day 5 and 6 and the lines were fading, so I was hopeful I might get a negative today. How today on day 7 the line is as dark as the first day again! Has anyone else experienced this? Looks like I'm going to have to wait the full 10 days to be released. Thanks
