Pill help!!

Poo

So I started the mini pop pill thing on the 20th of November (the day my period ended)

On the 30th my period started again (not when I would usually have it) and it was dark and a lot of uterus lining so I guessed it was just shedding)

I’m worried because I’m still on the period (not as much lining) and idk if it’s normal or if I should make an appointment :(
