does anyone know if digital tests are as sensitive as regular hpt's? ive taken three ept's all with the same faint posative but i was starting to think that maybe i was seeing an evap. line so i took a digital and it said no. and now im just confused. im curious as to how exactly a digital test reads the lines. i mean, if the digital test had a faint positve also would it detect it or would it have to be a strong line. i know im just driving myself nuts but was wondering if anyone had any further info on digitals.
