During pregnancy and especially after giving birth, the body has to deal with major changes that often disrupt the hormonal balance. For the psyche, a child means an enormous change. A young mother finds herself on an emotional rollercoaster.

With birth, bleeding begins which serves to heal the wounds in the uterus – the lochia.

Many women are not sure how long the lochia lasts and whether it leads directly into the first menstruation after birth.

The first menstruation after the postpartum period begins at least five weeks after birth. The exact timing varies from woman to woman and is influenced by various factors. 

Breastfeeding can delay the onset of menstruation

What does breastfeeding have to do with monthly bleeding?

The hormones that are released during breastfeeding are responsible. The hormone prolactin, which the body produces during breastfeeding, is needed to produce milk. Prolactin prevents new eggs from maturing and thus the next ovulation. As a result, the mucous membrane in the uterus is not prepared for a possible pregnancy and does not thicken.

Only in fully breastfeeding mothers, i.e. when breastfeeding at least every four hours, can the body produce enough prolactin to suppress ovulation. In these cases, the period only starts again after the child has been weaned.

Breastfeeding as natural contraception

Even if a woman is fully breastfeeding and the natural menstrual cycle has not yet resumed, this is no guarantee of reliable contraception. Ovulation may have already occurred even if there is no bleeding.

Even slight changes in the breastfeeding rhythm can encourage an egg to mature again. If the woman has had sexual intercourse during this time, pregnancy is possible even if she has not had a period before.

Even though breastfeeding has been proven to suppress menstruation in most cases, it is not a reliable form of contraception. Therefore, breastfeeding women should definitely consider suitable contraception.

The first period after weaning

For most women, menstruation starts again within two months after breastfeeding. But this also varies from woman to woman.

Many other factors can influence the return of your period. For example, a low percentage of body fat is considered a reason for a delayed cycle. Stress and emotional strain can also be reasons for a missed period.

However, if menstruation has not resumed three to four months after weaning, it is advisable to consult a doctor for clarification.
