I had a medical abortion at 5 weeks in which bleeding happened for 11 days in which enough of clots of passed(no abnormality) and had pain which decreased bt as bleeding stopped, it increased. After 13 days of started bleeding there is still pain in abdominal which is somewhat high. I don't have any kind of symptoms of infection except very light chills sometimes  (no fever above 38°C, no odour or discharge from vagina, no bleeding, every symptom of pregnancy went normal and no other problems). I never took any painkillers or antibiotics. Are there possibility of infection? If yes then what type of and how to cure it
