Thoughts?

So Tuesday I got the depo shot. They told me to wait for seven days for to have sex without a condom. Well my dumbass forgot in the moment. And I had sex without a condom the weekend before I got the shot but I was on the pill. How likely do you think it is that I’m pregnant. And before someone shits on me. I know anytime I have sex I risk getting pregnant. I just need advice.
