Took this yesterday morning, and it showed positive within about 30 seconds. According to the app and my last period, I should be about 5 weeks 5 days today. Once I started looking at posts here though, I got paranoid about having used a blue dye test. It showed up immediately and isn't faint at all, so I should be good, right?? We've been trying for almost 4 years, so I'm nervous to get too excited!!
