Emergency contraceptive pill. To test?

Dear Doctors, I had unprotected intercourse with pull out method on 24th aug. But it somewhat failed since I felt wet and leaky in the next morning. Had ipill on 26th aug - 32hrs after the act. Initially had cramps but discharge was clear and stretchy, typical to my ovulation, till 28th aug. 10days after the pill and 12 days after the act, I don't have much abdominal cramps but I am feeling very bloated, gassy and uneasy, since the last 2 days.  Increased fatigue is also there due to bloating. I had Digene, it didn't help.. Vaginal discharge is now scarce but white and sticky. I also did a HPT on 2nd Sep, which came as negative. I am expecting my periods on 12th Sep (+- 2days) and have not had any bleeding yet. I am worried since even after taking the ipill, my discharge remained same like during ovulation, for the next 2 days.. Are there still chances for pregnancy and what would be the best time to test?
