Postpartum Irregular Periods: Why & When They Normalize

Postpartum periods are often irregular for several months as hormones rebalance and, if breastfeeding, prolactin fluctuates. Most women see cycles normalize within six to twelve months. If irregularity persists beyond that or is severe, check with a doctor.

  • Flow may differ from pre-pregnancy.
  • Breastfeeding extends irregularity for many women.
  • Most cycles normalize within six to twelve months.
