I had d&c few days ago. I was feeling ok but today I feel abdominal pain. Like cramping and dull pain. Is it normal?

Pain. It is not unusual for one to have cramping a few days after a d & c. If you have severe pain, fever, foul smelling vaginal discharge, or just not feeling well it would be wise to speak with your gynecologist about your symptoms. He or she may need to see you earlier than scheduled.
