Period 3 time this month???

I took a plan b on December 23 and bled on December 31-3.

I then bled again January 12-16. I have also started to bleed again today January 24.

Is this normal? Should I go see my gynecologist because I have taken plan b before and I haven’t had this happened.

I am also on progesterone bc and I am near the end of my pack but I still have till next week.
