There is significant individual variability in how soon ovulation occurs after childbirth, which may be around four to six weeks, or it may take six months or even longer.
After giving birth, a woman’s hormone levels, uterine lining and cervix all need about four to six weeks to recover. If you choose to formula-feed after delivery, the ovulation function usually recovers faster, and may be restored in about four to six weeks.
However, if you choose to breastfeed, breastfeeding will increase the level of lactogen in the mother’s blood, which will have an inhibitory effect on the ovulation function of the ovaries. Therefore, compared with formula-feeding mothers, breastfeeding mothers resume ovulation relatively late, may be about six months, or after the end of breastfeeding before ovulation resumes, with obvious individual differences.
