When will I have a normal cycle again?

Cherie • ONE AND DONE! that`s what i always say.....
It's been just over a year since I had my child, and about 4 months since I stopped breastfeeding him. I started getting my period just before i quit breastfeeding, and got it every 2 weeks until this last time. Now it's been 5 weeks, and I'm not pregnant. Though I've also been off if birth control for about 3 weeks. I'm confused at what to expect from my body.
