So many Questions

So I took a first response and it came out positive but the line faded and is really hard to see now.. so I took a clear blue and a line came up within the time frame but over time has gotten darker.. I’m really confused as I started light bleeding today nothing like a regular period, I have been doing tests all week and they have all been negative up until this afternoon after I started bleeding, I don’t want to get excited (I already am tho) lol what’s your opinions girls
