Looking for an opinion!

Good morning ladies, hoping you can give me some opinions (I know it is still early) but do you think my tests are getting lighter, darker, or are the same? I thought they look the same, hubby thinks darker. Iui was on the 16th and I took a booster of ovidrel on the 21st (5dpiui). I was hoping to watch it get lighter so I knew when I tested next week it would be accurate.

Top test: 1 day post booster / 6dpiui

Middle : 3 days post booster / 8dpiui

Lower: 5 days post booster / 10dpiui

Thank you!!
