Thanks for the query.
it will take sometime for regeneration of the endometrium.
As you had bleeding for 6 days after taking pills the chance of continuation of the pregnancy
is very less.
You can wait for one more week possibly by that time you will get periods, if not consult gynecologist once and undergo ultrasound
once which will rule out the possibility of continuation of the pregnancy.
Then with your doctor's advice you can go for tablets for withdrawal bleeding.
