How long does lochia last after a normal vaginal delivery?
Vaginal lochia after a normal delivery usually lasts for 4–6 weeks. For the first 3–4 days, it is bloody lochia, which gradually turns into serous lochia and finally becomes white lochia before disappearing completely. The overall discharge volume gradually decreases over time. If lochia persists beyond 6 weeks, has an unpleasant odor, or if bleeding increases, prompt medical attention is recommended.

In the early postpartum period, bloody lochia contains a large amount of blood, appearing bright red and relatively heavy in volume. After 3–4 days, as the endometrium heals, the blood loss decreases and the discharge gradually changes to pinkish-red serous lochia, which typically lasts about 10 days.
Following the serous stage, lochia becomes richer in white blood cells, turning white or light yellow with a thicker consistency—known as white lochia—which usually lasts 2–3 weeks. If the mother recovers quickly, the duration of lochia may be shorter; recovery delays may slightly prolong it, but generally not beyond 6 weeks.
After childbirth, frequently change sanitary products and keep the perineal area clean and dry. Wear loose, breathable cotton underwear. Avoid tub baths and sexual intercourse to prevent infection. Light walking can help promote lochia expulsion, but strenuous exercise and excessive fatigue should be avoided.
