Line progression pregnancy test

hello! I want to know if the lines are progressing well, I started testing 4 days before my period and got a vvvfpl, then tested yesterday and got a vvfpl now today i can see the line much better than i did yesterday and Saturday. Here are the pics

saturday (7/13) reg and tweaked

sunday (7/14)

today (7/15)

Does it look like it’s getting darker and darker? I’m supposed to be getting my “period” on Wednesday, but I don’t think I am, I’ve been worried about cramping and such but I’m praying this is a sticky bean. I’m making an dr’s appointment today to confirm
