hi doctor my baby is 7.5 months old, I am a breastfeeding mother I got my periods regular after the next month I delivered my baby. for few months my periods were on exact after 30 days but from last 2-3 months sometimes I am getting on 28 days, 32 days, 26 day. what can be the reason for this. even before pregnancy my periods were regular on exact 28 days. what could be the reason for irregular periods now.
