It’s been a month after my wife's normal delivery but the bleeding has still not stopped. What could be the problem?

For some women, lochia may last for 6 to 8 weeks after delivery. If your wife is bleeding profusely, or if the lochia is bright red or has a foul smell, bring her to the doctor. http://sg.theasianparent.com/lochia_postpartum_bleeding_singapore/

If the bleeding is on and off and very light, do not have to worry. If it is still heavy bleeding, please visit gynae as soon as possible to rule out any infection.

thanks
