I gave birth via c section on the 27th december. i have been experiencing a brownish smelly discharge for 3 weeks + now is it normal?

No: The normal post childbirth involution process and uterine shrinkage produces a brownish to yellow discharge over 4 to 6 weeks.(lochia) If the discharge is "smelly" and still present now 6+ weeks later, you need to see your OB MD to look for retained instruments/packs, products of conception, or an infection. Make an appointment soon.

No: Likely cause is a vaginal infection. Usually, bacterial vaginosis/vaginitis which is an alteration of the vaginal flora. Less likely is a uterine infection, endometritis, but this usually causes abdominal pain and possible fever. See you doctor for an evaluation.
