White discharge from the nipples during pregnancy is a normal physiological reaction, due to the increase in the level of hormones in the body after pregnancy, resulting in an increase in secretions from the breast ducts. When bathing and cleaning the nipples during pregnancy, pay attention to gentle movements and do not use excessive force to avoid damaging the nipple skin. In late pregnancy, do not over-stimulate the nipples to avoid causing contractions. During pregnancy, white liquid-like discharge from the nipples is considered to be milk, and it is normal to have a small amount of milk secretion in late pregnancy. If there is blood-like discharge from the nipples, it is considered to be related to breast lesions and requires prompt examination at the hospital.
