Can this be a possible pregnancy? (Post depo shot)?

I recently got off the depo shot, I was supposed to get it again around late June but I never went back, so the last shot I got was in late March. for the past two weeks my sex drive has been extremely high and my discharge had increased, so I thought I was ovulating and I had unprotected sex about twice last week and both times my boyfriend came in me, so a week has passed since then and I just want to know what my chances are of becoming pregnant, I was on the shot for about 8 months and this last shot I got in march stopped my periods completely. the last period I had was in May. I have been off the shot technically for about 3 months going onto 4 months, I really want to have a baby so if anybody has been on the depo shot please give me some good news or feedback. I also had that white milky discharge today.
