Depo and Pregnancy

Hello all, so I’ve never posted on here before but I recently went back on my depo shot but the period had already ended when I got it... not spotting or anything, I also didn’t think and had unprotected sex multiple time & my significant other obviously got off multiple times in me... I didn’t even think about the seven day wait with the shot.... now I am 10 days late & I’m having pregnancy symptoms, I was wondering what the odds of pregnancy and depo are. I know they are typically very slim but clearly neither one of us thought the situation through.
