Lochia progresses in the following order:

A) Fundus below the symphysis and not palpable:
The process of involution refers to the shrinking and returning of the uterus to its normal size and position after delivery. By postpartum day 14, the uterus should be largely involuted, with the fundus no longer palpable above the pubic symphysis. This is a normal finding, as the uterus typically shrinks to its pre-pregnancy size over this period. The fundus should be at or below the symphysis pubis and should not be palpable after about two weeks postpartum, indicating that the involution process is proceeding as expected.

B) Moderate, bright red lochia:
While bright red lochia (also known as lochia rubra) is common during the first few days postpartum, by postpartum day 14, lochia should have transitioned to a serosa (pinkish or brownish) or alba (white or yellowish) appearance. Bright red lochia on day 14 would suggest a possible issue, such as retained placental fragments or uterine atony, and would require further evaluation.

C) Breasts warm, firm and tender:
Breast tenderness and firmness can be normal in the early postpartum period, especially as milk comes in. However, by postpartum day 14, if the breasts remain tender and warm, this could indicate mastitis or engorgement that hasn't been resolved. While some tenderness may still occur, it should have decreased by this point. If tenderness persists, further assessment would be needed.

D) Laceration slightly red and puffy:
Postpartum lacerations or episiotomy sites should begin to heal within the first few days, but slight redness and swelling might still be present at two weeks. However, puffiness or continued redness after 14 days may indicate poor healing, infection, or other complications, which requires further evaluation and intervention. Normal healing should show a decrease in redness and swelling by this time.

A) Prolactin:
Prolactin is the primary hormone responsible for stimulating milk production in the postpartum period. In breastfeeding mothers, prolactin levels remain elevated, especially during the first few weeks after delivery, to support lactation. This hormone is released in response to suckling and is essential for maintaining a steady milk supply. Elevated prolactin levels help establish and maintain breastfeeding during the early postpartum period, even as other pregnancy-related hormones begin to decline.

B) Estrogen:
Estrogen levels drop sharply after childbirth, as the placenta is no longer present to produce this hormone. The decline in estrogen is one of the factors that helps initiate lactation. While estrogen rises later during the postpartum period as the body returns to its non-pregnant state, it is not elevated during the immediate postpartum period in breastfeeding women.

C) Progesterone:
Similar to estrogen, progesterone levels fall quickly after delivery. Progesterone is involved in maintaining pregnancy, and its levels decrease significantly once the placenta is delivered. A reduction in progesterone is one of the hormonal changes that triggers the onset of lactation. It does not remain elevated in the immediate postpartum period.

D) Human placental lactogen (hPL):
hPL is produced by the placenta during pregnancy to support fetal growth and prepare the breasts for lactation. However, after delivery, hPL levels decline rapidly because the placenta is expelled. It is not elevated in the immediate postpartum period.

E) Relaxin:
Relaxin is a hormone that helps to soften the cervix and relax the ligaments in preparation for childbirth. Its levels are elevated during pregnancy and drop significantly after delivery. It does not remain elevated in the postpartum period, particularly in breastfeeding women.
