Please help

My last period was May 10th. Previous to that period, I had stopped taking birth control. On May 10th I started a new pack. I took about a week and a half of that pack and then I stopped taking birth control because I've decided I don't want to take birth control anymore. It's now July 13th and I still haven't had a period. I haven't been sexually active since my last period so I highly doubt it's pregnancy. Has anyone else every expirienced this or something similar? Or have any comment?
