Anybody ever taken a digital test apart

Ok so I took a clear lie digital test about 2-3 days ago and it said not pregnant. But then today I woke up with a head/neck ache so bad that I was nauseous all day. But while laying in bed trying to get it to go away I started googling it digitalis can give a false negative. So some sites were saying yes then one comment said they pulled it sort and the strips were pod but for the test to read it as pod it needed to be higher hcg levels. So I pulled the one I took a few days a go apart and I could see a very faint line so I took the second test and again it told me not pregnant but the strip inside also has a faint line even after having just peed on it could it be and evap line or a faint positive top strip is from today the bottom strip is the older one idk how well it show in this pic
