Should I Take A Test??

So I was suppose to start my period on the 10th of this month. It did not come on the 10-11th. At night on the 11th I started spotting (light). On the 12 I got my period. On the 13th to now I’m back to spotting

This is not normal for me. My period usually last 5 days.

-What are your thoughts on this?

-Should I even bother to test?
