Is there any way I could be pregnant?

Patient: I had my first depo birth control shot on April 7 2014 I had sex on June 4 and June 17 and I used a condom every time. Nothing has ever gone wrong with the condom, and he has never enjaculated while in me. I took a test first thing this morning and it came back negative. Could I be pregnant? I am just dreaming myself out.

Doctor:
