Thanks for the query.
The chances of pregnancy
are less as you had intercourse on around 6th and 9th day of cycle, in case of regular periods ovulation is rare on that time.
When you took emergency pill in the first half of the cycle it will prepone the periods.
That may be responsible for your bleeding September 6th.
So as now your last menstrual period is September 6th, now you wait for one more week possibly by that time you will get periods.
