Where is my period???

Erin • Celebrated 5 years in November. Expecting our first Jelly Bean September 2016 ;)
I stopped taking the pill after almost 6 straight years August 29th because I'm TTC but I haven't had my period yet and I know I'm not pregnant. Has anyone else experienced this? I want to have my period so I can track ovulation. How long will this take? I really want to be pregnant soon!
