They are developing, everything is going well!
Nature knows what it’s doing, from the beginning of pregnancy onwards, hormonal changes increase the size of the ducts and glands in the breasts to prepare them for breastfeeding. As a result, the breasts develop, their network of bluish veins becomes visible, the pigmentation around the nipple area may become more intense and a feeling of tension arises that is sometimes painful. All completely normal. It is also normal, depending on the hormone level, for breast size to increase, this differs from one woman to another. The changes are slight in some women and spectacular in others, your bust will reach its maximum volume a few days after delivery with milk let-down. If you are not breastfeeding, the sudden drop in hormone levels will lead to a rapid decrease in the size of your breasts. If you are breastfeeding, the process will be more gradual. Whichever is the case, the sooner you give your bust the appropriate care, the better you will preserve their firmness.
