Although there may be times when you notice more or less discharge, lochia itself doesn't usually stop altogether only to start up again. Sometimes, the bright red discharge that you had in the first few days after you gave birth may also return.
Can lochia go and come back?
For some women, their lochia can stop or fade and then return, often between week 5 and 8 and it can occur even after a week or more of nothing. While it is possible this is the return of your menstrual cycle, it is unlikely for most women.
Is it normal for lochia to stop and start again?
Conclusions: Lochia lasted substantially longer than the conventional assumption of 2 weeks. It was common for postpartum bleeding to stop and start again or to be characterized by intermittent spotting or bleeding. Return of menses is rare among fully breast-feeding women in the first 8 weeks postpartum.
