Kick start my period

Is there anything I can take or do to have a period again? I am 19 and married. Before that I was put on bc for 5 years because my mom didn't want me to become her and not finish high school. Dh and I are ttc but not actively trying. We just want to begin the process so that we both know we are healthy and able to conceive when the time comes. I have been off bc for almost 4 months an nothing. No spotting, no period symptoms, just nothing. I have battled a lot of cysts in the past and I just want to move forward and have a period. Is there anything that you ladies know of?
