Women should not take birth control pills while breastfeeding. Birth control pills contain a lot of hormonal components, whether short-acting or emergency contraceptives, which can be sucked by the baby through breast milk metabolism and have a negative impact on the baby’s growth and development. If you want to use contraception while breastfeeding, it is better to use intrauterine device or penis condom to prevent pregnancy, which is safer and will not adversely affect the growth and development of the baby. When breastfeeding, women should rest properly, live a regular life, pay attention to increasing nutrition in their diet to help their body recover and improve the quality of milk, and not eat cold, spicy, stimulating food or take drugs.
