Periods and Birth Control

In July I took myself off birth control because I was sick of paying almost $100 for it. Plus I'm happily married and we don't care if we get pregnant at this point in life. Since I came off the birth control, I've only had 2 periods. It's been 106 days since my last period and I'm NOT pregnant. Was hoping some of you out there have experienced similar things after coming off birth control. How long did it take to get your period back?
