What physical change might a woman notice regarding her breasts during the third trimester?

During the third trimester of pregnancy, a woman commonly experiences an increase in breast size and tenderness. This change is primarily due to hormonal fluctuations, particularly elevated levels of estrogen and progesterone, which stimulate the growth of the milk-producing glands and prepare the breasts for lactation. As the body gets ready for breastfeeding, the increased blood flow and changes in the breast tissue contribute to sensations of tenderness and fullness.

This phenomenon is part of the body's preparation for nourishing the newborn after delivery. Many women notice that their breasts not only feel heavier but may also be more sensitive to touch during this time, which is an entirely normal physiological response to pregnancy. These changes can also be accompanied by visible signs such as the darkening of the skin around the nipples, but the primary aspects prominent in this context are the increase in size and tenderness.

Other options reflect changes that typically do not occur or do not represent the most common experiences during this stage of pregnancy. Therefore, the correct choice highlights a significant and expected physical change in the breasts during the third trimester.
