Has anyone ever gotten an indent or evap on a Wondfo HCG test? I took one at about 5:30, didn't see anything and then went to dinner with coworkers. I came home about 8:00, and I can see a second line on the test. I know since its past the timeframe that it very well could be an evap, but I didn't think this brand was known for evaps. Has anyone experienced this before?
