Thanks for the query.
Usually by 4 weeks of post cesarean section the lochial discharge will stop.
As you had increased blood flow after 4 weeks and passage of clots there is possibilities are:
. As you had emergency section there is more possibility for infection than in elective section. If infection spread to tubes that can discharge infective material into the abdominal cavity that can cause pain abdomen.
-If you are not breast feeding the menstrual cycle can start early and that may be responsible for your increased blood flow.
So you better consult your doctor once and get examined to find out the actual cause of your problem.
