Okay is this normal?

Okay so for the past how many months my period has been 2-5 days late, last month it was early and now so far late again..is it normal for it to be so irregular? Before it started changing every month it was pretty regular and i would know when i would get it..now i honestly have no clue..today i felt nauseous when i was eating, super tired, not really bloated like i usually am (when af shows up) gassy, my acne is actually clearing up..boobs kinda tender (but i worked out on Thurs), i just want it to be normal or be pregnant like aghhh
