birth control question

i just recently started the pill. today i took my 11th one. im on emoquette, a combination pill. reliable websites told me it starts working after a week. i know its in my system bc im experiencing side effects. yesterday, after my 10th pill i had unprotected sex w my boyfriend, but he still pulled out. he is EXTREMELY worried im pregnant bc i did not finish the whole first pack as my dr instructed me to do so. however im not worried bc the package & websites said i was okay after a week. & now bc my boyfriend is freaking out, im starting to feel a little uneasy about it too. thoughts?
