The breastfeeding period is the period when the mother breastfeeds her baby, that is, the period between the start of breastfeeding and the end of breastfeeding, which is usually called the breastfeeding period. However, the length of the breastfeeding period varies from woman to woman, and the length of the breastfeeding period can usually be adjusted according to individual circumstances. Generally speaking, women do not menstruate or ovulate during breastfeeding, but this is not an effective means of contraception.
