lines getting darker than fainter?

So I'm two days missed AF. My line was pretty dark yesterday but it was 2nd morning urine then this morning I tested with FMU and my line seems fainter? I took a digital test and it said pregnant still. I don't know what to think. The first photo is a collage leading up to yesterday's obvious pink line. And the 2nd photo is the tests I just took. I'm nervous bc I had a chemical last cycle. My boobs are not super sore like yesterday but still tender. Should I worry or should I chill and wait until my first OB appointment.
