TTC After Birth Control

I was on birth control since 16 (11+ years) and I quit taking it mid cycle in June. Had my period 2 weeks after my last period ended. This messed my charts all up. So, my FW and ovulation time came around: no change in CM or rise in temp. 
Has anyone else abruptly stopped BC and started TTC? I want to know someone else's experience as far as how long it took to conceive or at least how long it began for AF to become regular.
