You should not breastfeed while breastfeeding. Emergency contraceptive pills mainly contain highly effective progestin ingredients that can cause endocrine disorders, and after taking them, the milk will also contain these ingredients, which will affect the child’s health if absorbed through the milk. If you are breastfeeding, you should not breastfeed your child within 72 hours of taking the pill, but only after that time can you continue to breastfeed your child. The best way to avoid ovulation is to use a condom during intercourse, which is the safest and most reliable way to achieve the purpose of contraception without affecting the health of women and children.
