2 months of birth control

My obgyn put me on birth control for 3 months to help with a cyst and then start TTC. He says it was like a 1in cyst. i have been on BC for 2 months, i am dying to start ttc. Should i wait and finish the 3 months on BC or should i stop and start ttc. i have an appt with my obgyn next month to stsrt the process. im want to ttc before seeing him. :0
