Normal lochia vs Abnormal postpartum bleeding or infection
How to tell Normal lochia and Abnormal postpartum bleeding or infection apart when a board question makes them look alike.
Normal lochia decreases and changes color without systemic symptoms; abnormal lochia is heavy, foul, febrile, tender, or recurrently bright red.
Side by side
Normal lochia progresses from rubra to serosa to alba over weeks, with decreasing amount and no fever, foul odor, uterine tenderness, or hemodynamic instability.
Abnormal lochia includes excessive bleeding, large clots, recurrent bright red bleeding, foul odor, fever, uterine tenderness, or signs of retained products or endometritis.
Normal postpartum uterine involution sheds decidua and blood products in predictable stages as the placental site heals.
Retained tissue, infection, subinvolution, trauma, or coagulopathy can disrupt healing and cause abnormal bleeding or discharge.
Stable vital signs, expected color transition, improving volume, and absence of uterine tenderness support normal lochia.
Fever, leukocytosis, uterine tenderness, foul discharge, ultrasound retained products, or anemia support abnormal postpartum pathology.
The trap
Postpartum discharge is expected, but amount, odor, fever, pain, and trajectory decide whether it is normal.
The repair move
For postpartum discharge, compare color stage and trend with fever, odor, pain, and bleeding volume.

CoreA 28-year-old woman is 10 days postpartum from an uncomplicated vaginal delivery. She reports light pinkish-brown vaginal discharge that has gradually decreased in volume over the past week. There is no fever, foul odor, abdominal pain, or large clots. Which assessment is most appropriate?
Show answer and explanation
Answer: A. Normal lochia (transition from rubra to serosa). Normal lochia progresses through three phases: rubra (red, days 1-3), serosa (pink-brown, days 4-10), and alba (yellow-white, days 10-28); decreasing volume without fever, foul odor, or hemorrhage is reassuring.
Why the other choices are tempting
- B. Endometritis presents with fever, uterine tenderness, foul-smelling discharge, and leukocytosis.
- C. Retained products cause persistent bleeding with an enlarged tender uterus and ultrasound findings.
- D. Secondary postpartum hemorrhage is excessive bleeding between 24 hours and 12 weeks postpartum.
- E. Subinvolution of the uterus presents with prolonged heavier-than-expected lochia and an enlarged uterus.
