Period Or Spotting ?

I took Plqn B on November 19 in 34 hours.

I bled December 1 which was almost 2weeks after I took the pill. My expected period was supposed to be December 1. I’m not sure if it’s actually my period right now or if I’m just spotting from a side affect of plan b. Last time I took plan b, I bled very little and had no cramps. Then got my period a week later. This time I bled a bit more and had cramps as if I was on my period. That’s why I’m not sure if it’s spotting from the plan b or my period....
