Period after miscarriage?

I was wondering how long it took everyone to get their period after miscarriage. I had a miscarriage on september 8th which lasted 8 days and im supposed to have my period by now but i have no symptoms. My pms starts like 10 days before so i KNOW its coming. My bbt chart has been all over the place. Negative ovulation strips. I dont know whats going on. How many weeks did it take from the start of your miscarriage til the 1st day of your period? TIA
