I had the same issue after having my son last year. I called the doctor like 3 months later and they asked when did I stop bf? I said I never started. At any rate, they gave me an oral packet of pills to induce my period . . . I then went almost another 2-3 months w/o a cycle. . . got another round. . . this time was only 6 weeks . GOod luck! I would just call the doc and ask for the pill!
