Can you be pregnant if you used the MAP 4 times in a row and had a period a week late lasting 5 days?

I'm not sure what it means to use a MAP 4 times in a row, but I can with all certainty say that if you had your period (and know it was not just spotting but a true period, as it sound because it lasted 5 days) then that would mean you were not pregnant at that time.
