Period. plz read😊

So I started my period for the first time last June, I had about two regular cycle periods that lasted about 5-7 days. Then it got SUPER irregular and I don’t think I ever had a normal cycle again. Pretty much all year I was always stressed in class cause I never New if I was bleeding or not I got mostly just a lot of discharge but sometimes there would be a little blood but eventually I got used to it and just wouldn’t put a pad on cause it would always just be a tiny bit and would just go away. So it was like that for a while but then it just stopped and I haven’t had any blood for about 6 or 7 months. It’s nice not having a period but I would really like to know why my period just disappeared😂 so anyone know anything???
