Hi H., I breastfed my second child for 2 years, and my period started when he was 12 months old. When it started, I was regular immediately, having a period every month. I've always been very regular though. If you stopped breastfeeding completely, your body should start getting ready for a cycle very soon, so if you do not want to get pregnant again right now, I would be very careful because it's hard to tell when you are going to ovulate. Good luck!
