If you read the test past the time it’s considered invalid. So if it says not to read results after 5 minutes. Don’t. I’ve had text that are negative and after sitting they produce an evap line. And I still wasn’t pregnant.
Retest. Only wait 5 minutes, anything past it is considered invalid
I'd say (if you have more tests after all this) to try again tomorrow morning because right now I feel like I'm imagening things too and don't want you to get excited 😂😂
