I had unprotected sex on day 6 of my cycle and took a post pill on the 7th. on the 8th and 9th i had sex again using the pull out method and i didn't take a pill afterwards, am i safe?

Not necessarily. Pull out method is not reliable. If you miss your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions carefully. Wish you good health! If you do not wish to be pregnant, use contraception all the time, every time.
