Is this normal?

Hi, Im a teenager who got her period for abt 10 months ago. And I need some answers for a "beginner".

So every Period for me has litteraly been so different.

Some (especially in the beginning) every day was pure little bit of brown blood and just lasted around 3 days

I have only once experienced a "normal period" and I dont have a cycle , it kinda just comes when it wants too

But one thing that has been in common with every period (exept that normal one) Is that my day 1 and 2 are always a little brown blood, so little that I only notice it once I got to the bathroom

I dont really have bad cramps yet, i feel them but I doesnt really bother me

But this time , its different in a way that Ive expreienced before but still, im on my day 6 and im bleeding like crazy , its like my blood increases by day starting from very little and as said looking back this was familar

So thats that, has anyone else have this or has any tips? any response is helpful so thanks!! Byeee!!
