The first symptom is that the volume of the breasts will become bigger, because when a woman is pregnant, the function of the endocrine system will be enhanced, and more estrogen, sex hormones, progesterone, prolactin and so on will be secreted, and these hormones can promote the division of the breast cells as well as the value-added, which will lead to a certain increase in the volume of the breasts, but there is a certain range of enlargement. The second symptom is that women’s breasts will become softer during early pregnancy. This is also because during early pregnancy, women’s breast cells will accumulate more fat, resulting in women’s breasts becoming softer. The third symptom is that there will be some secretion from the nipple during early pregnancy, such as white or yellowish mucus, because there is a certain amount of milk formation during early pregnancy, and part of the milk can be discharged through the milk ducts, so it leads to secretion from the nipple.
