Am i pregnant?

my last menstruation was on July 14. I had an intercourse on august 1. The next week,i experienced having a very slimy and clear discharge with blood. it happen for 3 days. everytime i wash, there is this kind of discharge. on the 4th day, i experienced having a very light menstruation which lasted an hour. on August 15, i waked up having a headache and feels like my whole mouthand teeth is numb and aching too. August 23, i experienced having cramping which usually happens a day before my menstrual cycle. I also experience slight pains on the side of my hips. then its gone and i don't have my mens. does it mean i'm pregnant?
