Faint?

I am new to all this so i’m asking for some help. The first two are the same day from yesterday and then last 2 are from today. One in the morning, one in the afternoon. Are these positive? What should I do? I took a first response test yesterday night and it was negative.. so should i wait a few days and try another first response? Am i pregnant?

Also i’m sorry if these seem like dumb questions, i’m just new to this , and shocked!!
