I wouldn’t worry, I would just take another test!
Yeah they tend to do that when they dry mine did as well ( the red dye ones) after a day or 2 so I just tossed them
I’d definitely just do another test maybe tomorrow to give it 48h to get darker for reassurance 🤞🏻
They're supposed to be binned once you've looked at them as they can change. The digitals can stay for 6 ish months though
Congratulations!
Could be urine a little diluted
Forgot to add: I haven’t retaken the tests, they’re the same tests I took yesterday, the lines are just now fading off the test
