I delivered my baby on Nov 23rd. During first postpartum visit my gynac told that for some breastfeeding ladies it may take 3 or even 6months to get their periods. But within a month I got my periods on 26th Dec eventhough my baby is on exclusive breastfeeding. Intercourse happened after 4 weeks of delivery. Whether that could be the reason for my period? Experts please tell whether it's normal.
