Early positive 3week 1 day

La

Anyone else ever have a positive this early?? First day of last period was 9/23. Next period is due 10/23 and I got a positive test on 10/14. We only had sex on 10/7 and 10/9. I just feel it is super early to have a positive as I never had symptoms or found out this early with my other two kids. And it really isn’t even that faint.
