Well I have four children and the last three I used a one dollar EPT pregnancy test from Dollar General. My first son I was just a day late and decide dto get one. I heard the ones for only a dollare worked so I decided to give that a try first! It turned positive right away with the convenience of two lines that showed up pink. If it is negative then only one line should appear. It showed within 20 seconds and was completely noticable. My second son was pretty much the same thing. We was trying so I took a test the day I was supposed to start and could tel imediatly that the second line was there....
