Boyfriend came in me

I've been on depo for about 2 weeks now and on the first of September my boyfriend came in me, my question is what are the chances of me getting pregnant? He always pulls out or he'll wear a condom just in case but this time we were careless and I let him cum in me, but I just have a little voice in the back of my head questioning about pregnancy idk opinions?

-the clinic told me after 7 days I'd be covered when I got the shot
