Period question

So my first period was around January 30th to February 6th it lasted longer by a few days. How long does it tAke to get back to normal? It’s my first log in the Flo app so I know it isn’t truly accurate but either today should be my start date or I’m a few days late. Normal? I’m worried I’m never late. Being one day late is what told me I was pregnant lol
