birth control possible pregnancy

Mia
So I was on the depo shot from September 14th 2016 to December 14th 2016 the last day to get the shot was December 14th and I skipped it because I had been losing a substantial amount of weight and my doctor was concerned and told me to get off of it. I had been having unprotected sex while on the shot and after as well and he ejaculated inside every time even after I was on the shot. Is it possible I could be pregnant. I heard it's very hard to get pregnant after depo. But I've also heard of some getting pregnant while on depo. I have not had a period yet since being off but I had been spotting a week after being off and now it seems I am ovulating already.
