DD is 23 months, still breastfeeding. My periods started again when DD was about 9months old and have been regular since then. Until this month, I'm more then 2 weeks late. Highly unlikely that I'm pregnant but did a test anyway today and it was negative. I'm wondering if they are getting irregular /stopping again because of the breastfeeding. Has anyone else had a return of regular periods and then later they stopped again while breastfeeding?
