I need answers

So... I ended my period on the 1st of sept.

Today is now the 17th..

I slept all day the 16th.. And today.. Ive had a head ache all day. So tired.. Light cramping on and off and when i wiped there was light pink on the toilet paper. One time.. Then ALOT of discharge and period smell.

Then I get home 4 hours later and still lors of discharge but no pink.

What can this be?
