my period is late

I first got my period 2 years ago and still to this day it's not regular. last month I got my period within 28 days,sometimes I got it within 33 days and it already happened that I got my period within 40 days! now,I'm on day 35 of my cycle and I still got nothing. it's so annoying! why is my cycle not regular?

ps.: I never had sex,so I'm pretty sure I'm not pregnant 😂
