I got my depo-provera shot july 16, 2012 and i had a appointment to on october 1st to go get my depo-provera shot but i didn't go get it then on october 7th i had unprotected sex is it possible that i can get pregnant because i missed my shot?

Yes. Possible.: To be very safe take emergency contraception (ec) now. See eclocator.Not-2-late.Com/ for info and nearby pharmacies. No prescription needed if 17 or older. Best 0-72 hrs after sex but may work up to 120 hrs (5days). Ec is not an abortion. Depo is scheduled every 11-13 weeks. July 16-oct 8 is 12 weeks so you are still likely protected. Chances of ovulation are less if this was not your first shot.
