short cycle women

Before my first child I was a 22-24 day cycle, most commonly 23 days. Now I am a 24-25 day cycle after having a kid. I took a test on the morning of the 26th day (the morning after my missed period) and already had a pretty dark positive test.

So now the problem is that all the pregnancy apps say things to the effect of not being sure yet, and tests not being able to read positive until 5 weeks.

Is anyone in the same boat as me? Anyone have a positive test by the late twenties of their cycle? I have been a very disciplined tracker for years, so I know I am not wrong.
