The timing of menstruation during breastfeeding varies from person to person. Some women will have their period 3 months after delivery, while others will have their period 8 months after delivery. The timing of menstruation after breastfeeding varies greatly. Women who recover quickly may have their period as early as 3 months after delivery, while those who recover more slowly may take longer, up to 8 months or more, to have their period. Menstruation is associated with ovulation, but the absence of menstruation does not mean that ovulation is not occurring. It is important to use contraception when having sex while breastfeeding. If you are breastfeeding and your period comes late or doesn’t come, you need to go to the hospital for a sex hormone test to determine how well your ovaries are functioning, and follow your doctor’s advice on how to regulate it.
