After my first baby I had 2 episodes of spotting at 11 mo and 13 months followed by a period at 14 months. I got pregnant on that cylce and based on ultrasound was probably running about a 35 day cycle. After baby #2, I had spotting at 9 months followed by a period at 11 months. I again got pregnant on my first cycle but based on ultrasound it was clear that I was running a 40 some odd day cycle. Now this seems so crazy to me but my third baby is now nearly 20 months old and I've still had no period or spotting. I don't really get it. My memory isn't perfect but I feel like he's nursing less than my daughter was at 9 months old!
