The transition of lochia from rubra to serosa occurs roughly in which timeframe?

Lochia changes color as the uterus heals: red lochia (rubra) is common in the first few days, reflecting fresh blood and tissue; by around the fourth day the discharge typically shifts to pinkish-brown (serosa), which can last up to about day 10. This progression means the transition from rubra to serosa most often occurs between day 4 and day 10 postpartum. If it were days 1–3, you’d still expect rubra; by days 14–21 you’d expect lochia alba (yellow-white discharge) as the serosa tapers.
