LATE PERIOD

Hi everyone,

I have a question:) my period was late for a couple of days for the past 2,3 months, but then at the end I always get it. Now it’s late again (2days for now). I don’t know why is this happening, could it be because I am stressed and frustrated all the time? Or because I’m right now working during the night for the past couple of months?( american company)

Is there a chance that I am pregnant? Btw I’m almost 22

Pleaaaase help me! 🥺🥺🥺🥺
