Is milk leakage during mid-pregnancy a good or bad thing?
Generally speaking, whether milk leakage during the second trimester of pregnancy is good or bad mainly depends on its underlying cause and the overall health of the pregnant woman. The specific analysis is as follows:

Physiological milk leakage caused by hormonal changes is normal and can be considered a positive sign. During mid-pregnancy, elevated levels of prolactin in the body may lead to a small amount of clear or milky discharge in some pregnant women. If there is no redness, swelling, or pain in the breasts and no other physical discomfort, this indicates that breast tissue is naturally preparing for breastfeeding after delivery. It is a normal physiological response that does not require excessive concern—maintaining proper breast hygiene is sufficient.
Milk leakage accompanied by abnormal symptoms may be a warning sign and could indicate potential health issues. If the discharge is excessive, discolored (such as yellow-green, bloody, or pus-like), or associated with breast tenderness, lumps, red skin, or systemic symptoms like fever and fatigue, it may be related to conditions such as mastitis or mammary gland hyperplasia. In such cases, prompt medical evaluation is necessary to identify the cause and initiate appropriate treatment.
In daily life, choose loose, breathable cotton underwear and avoid tight clothing that may compress the breasts. After milk leakage, gently wipe the nipple and surrounding skin with warm water and keep the area dry and clean to prevent bacterial growth. Avoid forcefully squeezing the breasts to prevent damage to breast tissue. Maintain a light, nutritious diet and reduce intake of spicy or irritating foods. Stick to a regular sleep schedule, avoid staying up late, and maintain emotional stability and calmness to support overall well-being.
