Positive or evap

[Mamabear1921]

I've had 4 of these tests that look like this now, what do we think? All have appareared 30-40 mins after taking them. Thank you!

They're invalid if read after 10 minutes. Anything within the time frame? Clearblue always have lines for me outside the time frame when they're negative. I would pick up pink dye tests and read within the time frame for a clearer answer. Good luck OP!
