Lochia is the vaginal bleeding and discharge that follows childbirth. It contains blood, mucus and tissue from the lining of the womb and usually stops within about six weeks.
Lochia changes color as the womb heals:
Bleeding after birth can last up to 6 weeks. It usually decreases most in the first week, then slowly fades. Some people notice a short increase in red bleeding at around 7 to 14 days. Breastfeeding can cause cramps and a little more flow, because the womb contracts. Lochia happens after a vaginal birth and after a cesarean section.
Maternity pads are recommended rather than tampons or menstrual cups while the womb heals. Rest, changing pads often and washing hands before and after can help lower the risk of infection.
Contact a midwife or doctor if bleeding gets heavier instead of lighter, soaks a pad in an hour, or comes with large clots. Fever, tummy pain or discharge that smells unpleasant can be signs of infection and also need a medical check.
