Indent Lines or faint positive??

So Tuesday morning I took a frer and it had a faint pink line in the time frame, next day I took a clear blue pink dye that was stark white, then today I took an Internet cheapie that had the faintest hint of a line. What do you guys think? All pics are in the time frame. Are indent lines colorless? And evaps only show up after the timeframe right? I’m so confused on these results and don’t know if I should keep spending money on tests.. I don’t have a period to track but it’s been about 5 weeks since we dtd.

Frer: Monday morning

Clear blue: Tuesday morning

Internet cheapy: today( Friday)
