Menstruation and breastfeeding

The return from childbirth, which corresponds to the resumption of menstruation after childbirth, is an important period of transition for new mothers. Understanding how breastfeeding can influence this process can help to manage expectations and better plan post-partum care.

What is the return from childbirth?

The return of childbirth refers to the return of menstruation after childbirth. This marks the resumption of menstrual cycles and therefore the possibility of a new pregnancy. It generally occurs between 6 and 8 weeks after childbirth for women who are not breastfeeding. For women who breastfeed on demand, day and night, and who do not express milk, the return to childbirth may be significantly delayed due to the hormonal changes induced by breastfeeding.

Influence of breastfeeding on the return from childbirth

1. Hormones and breastfeeding: breastfeeding stimulates the production of prolactin, a hormone essential for the production of breast milk. Prolactin also has an inhibitory effect on ovulation, which can delay the return of menstruation.
2. Lactational amenorrhoea: as long as breastfeeding is exclusive and frequent, prolactin levels remain high, preventing ovulation and therefore menstruation. This period of lactational amenorrhoea can last from a few months to over a year, depending on the intensity and frequency of breastfeeding. The fact that baby sleeps through the night, that something other than breast milk is introduced or that you express your milk means that your period returns.
3. Individual variability: every woman is different. For some, periods may return soon after giving birth despite breastfeeding, while others may not see them return until their baby is weaned. Factors such as frequency of feedings, use of supplements and individual characteristics (such as body mass index and hormonal history) play an important role.

Signs and managing the return of nappies

1. Impact on breastfeeding: many mothers worry about whether a return to menstruation will affect their milk supply. In general, a return to childbirth does not significantly affect lactation. However, some mothers may experience a slight reduction in milk production or increased sensitivity of the nipples during their period. If this is your case, put your baby to the breast a little more often.
2. Contraception and breastfeeding: Exclusive breastfeeding can be used as a natural contraceptive method known as the Lactational Amenorrhoea Method (LAM), which is 98% effective provided certain conditions are met: the baby must be exclusively breastfed, without supplements, and feedings must be frequent (at least every 4 to 6 hours).

Return from childbirth and new pregnancy

It is important to note that the return of menstruation means that ovulation has resumed, making a new pregnancy possible. If a new pregnancy is not desired, it is essential to use an effective contraceptive method. Contraceptive methods compatible with breastfeeding include the copper coil, condoms and certain progestin-only pills. Consult your gynaecologist or GP for more information.

Conclusion

The return from childbirth is a normal and expected phase of the post-partum period, which varies considerably from one woman to another, particularly if you are exclusively breastfeeding. Understanding how breastfeeding influences this process can help to alleviate concerns and better plan for this transitional period. If you have any doubts or concerns, it is always advisable to consult a healthcare professional or lactation consultant for personalised support.
