I have unprotected sex with pull-out method with my boyfriend on the 4th oct and my period is supposed to due on 11th oct. will i get pregnant?

Sex leads to babies: Pregnancy is unlikely 7 days before an expected period. If worried about pregnancy, one can do a pregnancy test. A urine pregnancy test gives a reliable result 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon, and thus lead to a repeat test.
