depo pregnancy???!

My boyfriend and I had sex a little less than a week ago, and he finished inside me. We ended up ending the relationship and I've been having anxiety attacks since. (Bad break up). I've been on the depo shot constantly and regularly for two years now. Could I be pregnant or am I on the safe side? I haven't been very hungry, and idk if that's symptoms or just because I've had anxiety and panic attacks non stop.
