Positive after the time frame

**update - I got my BFP the day after these tests!

So, I know the tests are technically invalid after a certain amount of time, but here’s my question. My tests from the last two days never had an evap or any kind of line after the timeframe, but the one I took today has a line after sitting for 30 minutes, and it has color to it in person. Could this possibly mean anything? Has anyone else had this happen and you ended up getting a BFP later on? And yes I do plan on testing again so no need to tell me that 😋
