at 4pm on 8 dpo, on wondfo my second line showed up after about 1min 30sec(literally it was all white until then) and at the same time, i had taken an FRER, which showed up white until after 2 minutes and some seconds. as my pregnancy progressed, the faster the lines showed up even before the dye had a chance to go! if you're lines are showing up before 5 minutes id say they're not evaps!
