Whether breastfeeding or not, conception is impossible in the three weeks following childbirth. For fully breastfeeding mothers, this period extends to the first five weeks postpartum.
Breastfeeding alone is not a reliable contraceptive, though it can suppress ovulation in some women. To use the Lactational Amenorrhea Method (LAM) for pregnancy prevention, meet these three strict criteria: no return of periods, baby under 6 months, and exclusive breastfeeding day and night—at least 6 feedings daily with no more than 6 hours between them.
Every woman is unique. If feedings are spaced out or infrequent, your baby is over 6 months, or sleeping longer, ovulation can resume, leading to pregnancy.
