Please give me your advice :)!?

On June 20th I had for the 1st time with a guy I have been talkingto for over a year. He has had a vasectomy for 4 years and I was in week 11 of the depo provera shot. We started out with no condom then put one on mid way through before he d. Ive known him forever we grew up around each other in the same small town. I have been diagnosed with general anxiety disorder and Osessive compulsive disorder almost a year ago. I am terrified of pregnancy but I know I cant let that ruin my love life. I took a pregnancy test to ease my mind last night which would have been 16 days after it was negative........cant go on a missed period bc I have bled almost everyday since starting depo provera...which they say is normal......I know hes had a vasectomy but i still get freaked out do you think im free of pregnancy....i went to the gynecologist yesterday and they felt no need to give me a pregnancy test since I was still on my depoin the 12 week period of its coverage time. Im just a freak out please help!
