Doctor Me And My Girlfriend Had Sexual Intercourse On Tuesday

Doctor me and my girlfriend had sexual intercourse on Tuesday but I did not come just to be on the safe side i gave her ecp pills an today again we had unprotected sex I just penetrated her but then i stop. We're not sure if i leaked in her or no. So already taken the ecp pill does she have to take any other pill to prevent pregnancy? or the ecp which she took is still enough To stop the pregnancy before it occurs?
