Help!

So.. I posted the first picture Monday. It was faint and my period wasn’t due until Wednesday. I took another pregnancy test the following day and it was negative. But my period is now late so I took another pregnancy test and the super faint line is back! Could this be a chemical? Or an ectopic? Or is it even possible to be a healthy pregnancy? I called my midwife and she kinda blew me off and said just to take another pregnancy test in a week.

I have no bleeding. I had light brown spotting Tuesday but only once when I wiped.

(Both tests were read in time frame. First one is early response and second is fast response)
