I know I am crazy...

So I am paranoid obviously but I just need reassurance. The top two cheapies are a month expired lol so I bought another today...it appears to be getting darker right? This was not right when the test was taken...it was probably 15 minutes after. The top was yesterdays FMU and the second two were today after work. I just need to keep my sanity until I get my HCG results back on Monday. Its gunna be a lonnnng weekend lol
