Stopping the "mini pill"

My husband and I are TTC #2. Our first is 5 and was unplanned. I stopped taking ERRIN  on May 31 and was scheduled to get my period today, and haven't gotten it. I'm not sure how long it takes to get back a cycle? Or if I ovulated right when I stopped considering I felt cramping. Anyone have an experience with a progesterone only birth control?? I just want to start planning ovulation and such so we can start!! 👶🏼
