Okay so, when I've taken pregnancy tests before, I've never been positive, nor have never seen even a faint second line. I took one tonight, and and I looked at it, I swear I see a very very faint line. I even took the pic and zoomed in. My other app is telling me to wait 4 more days. I sent these to 3 of my friends in our group chat and they all say they see the second line. Opinions?
