Tested positive before period

Hi My last period is 11/9/2024 and i have been ttc for 2nd baby for 8 months. My average cycle is 40 days and my next expected period is due on 19/10/2024. However, my instinct told me to test on 14/10/2024 and it came out positive. I tested thrice. 2 with cheap kit and 1 with clearblue. All came out to be positive. Just curious if this means anything? For my first born, it came out positive only 1 day after i missed my period.
