Emergency pill help

Hey girls,

I started my period last Saturday 28th nov and

Nd I took emergency pill on30th as I usually have 4-5 days period I’m still spotting & still releasing blood is it normal as this was my first time taking the pill. 3rd dec I thought my period is over but yesterday I spotted again!! Feels like I’m back on period!

Also by DEC 28th I should have got my period but it’s 7 days late!!!

I’m stressed and don’t know what to do.

When should I be accepting my period?

Has anyone experienced like this before?
