Really confused

So I got a d&c on May 31st....kept taking tests to make sure the hormone was decreasing, yesterday yhought I was getting af as I had cramps and brown/pink spotting...I took a test (yes I took apart because I saw a line but wanted to get rid of the glare) and there was a line still. I took another test last night and they was a darker line...I couldn't help myself so I looked at the test in the trash this am an the line is darker..top test is test from Saturday - bottom test is test from yesterday..and as u see it got darker overnight and has color...but I am spotting like my period and boobs hurt!! Please tell me what u think! Is this my rainbow or an Evap line!!
