New to Femme tab 30/150

Hey gals, so Ive been on femme tab 30/150 for 12 days now (this includes the first day I started it). I took my first tablet on the first day of my menstrual cycle. Since that day there have been 5 sugar pills and 7 hormone pills. Am I protected against pregnancy if I decide to have unprotected sex on day 13 of my pill?
