Introduction
First, the color differs. Under normal circumstances, bright red lochia is discharged within three to four days after delivery. After some time, the lochia gradually changes to pink or brownish-yellow, and by approximately ten days postpartum, it becomes creamy yellow or brownish-yellow. In contrast, menstrual blood color remains relatively consistent, primarily appearing as dark red blood.
After childbirth, distinguishing between menstrual bleeding and lochia can be done by observing the color, duration, and volume of vaginal discharge. Women should undergo a postpartum physical examination at 42 days post-delivery; if recovery is complete, menstruation may resume normally. Postpartum menstrual flow is typically light, with dark-red blood. In contrast, lochia is initially bright red and heavier in volume. Mothers should maintain good vaginal hygiene to prevent infection.
How Women Can Distinguish Postpartum Menstruation
Color
First, color differs significantly. Within three to four days after delivery, lochia is typically bright red. Over time, it gradually transitions to pink or brownish-yellow, and by approximately ten days postpartum, it becomes creamy yellow or brownish-yellow. Menstrual blood, however, remains consistently dark red without significant variation in color.
Timing
Second, timing differs. Lochia usually ceases within four to six weeks postpartum, although in some cases it may persist until the onset of the first postpartum menstrual period. The first postpartum menstruation may occur as early as six to eight weeks or as late as four to six months after delivery—timing varies depending on individual physiology. The initial postpartum menstrual flow is often lighter and lasts approximately five to seven days.
Volume of Bleeding
Third, volume differs. Lochia is generally more abundant initially but progressively diminishes over time. By contrast, the first postpartum menstrual flow is often scanty and gradually returns to normal; however, total menstrual blood loss typically does not exceed 80 mL.
Characteristics of Menstruation
If lochia has transitioned to white (i.e., “white lochia”) and then, without apparent cause, reappears as bleeding resembling previous menstrual flow—or slightly heavier—but without other discomfort, this likely indicates the return of menstruation (“menstrual resumption”). Generally, most mothers experience slightly heavier menstrual flow during their first postpartum period compared with pre-pregnancy levels, and bleeding typically resolves within one week, requiring no specific treatment.
