Confusing cycle think I’m pregnant

Patient: I get my period on the 2nd of every month for the last 6 months its been like that, but in December I got it twice (on the 2nd and the 27th) which is incredibly unusual. I was wondering if this was possibly a sign I could be pregnant? I’ve been waiting to miss my next period to take a test which is in about 4-5 days now. So yea i’m just wondering if my hiccup in my cycle could of been a sign?
