a. In early pregnancy, the breast may feel full or tingle, and increase in size as pregnancy progresses.

The areola of the nipples darken and the diameter increases. The Montgomery’s glands (the sebaceous glands of the areola) enlarge and tend to protrude. The surface vessels of the breast may become visible due to increased circulation and turns to a bluish tint to the breasts.

b. By the 16th week (2nd trimester) the breasts begin to produce colostrum. This is the precursor of breast milk. It is a thin, watery, yellowish secretion that thickens as pregnancy progresses. It is extremely high in protein.

c. Nursing implication: Inform the pregnant patient to wear a good, supporting bra.
