advice please?

I just found out we were expecting yesterday. I took a cheapie and saw a line, but confirmed with a digital. Today I took another cheapie to see if my line was getting darker and to me it doesn't look any darker, but I took another digital and it said pregnant right away. Maybe I'm freaking myself out a bit. What do you ladies think? Darker or no? Top one is yesterday completely dried over night and the bottom two are from this morning not dried yet.
