The uterus is growing as the baby grows. The breasts will be growing more sensitive as they begin to prepare for lactation. Varicose veins, dark veins that develop around the breasts due to the increase in blood supply may appear. These veins do not appear on all women, but most experience them. Because of the hormone changes within the body, the areolae (the skin around the nipples) begin to darken. Montgomery tubercles (small glands on surface of the areolae) develop, and the nipples grow larger. A thick, yellowish substance called colostrum begins to discharge from the nipples. One may experience cramping or pain in the abdomen due to the growth of the uterus. Some of the common symptoms are growing breasts, abdominal bloating.
The baby size is about a size of a kidney bean, length of3/4th inch from head to bottom and a weight of about 0.04 ounce.
