Sex in the first 7 days of Depo Shot

BreAsia

Just was wondering does anyone have any insight because my doctors didn’t let me know this when I got my shot. My real period was Jan 21 through the 25/26. Longest period I’ve ever had so I decided to get on the depo. We had sex last day of my period the 26. I got my first depo shot the 28 and we had sex again the 31 and I also had a lot of creamy cm that day. I know depo is working because I have no cm right now but I kind of usually don’t after ovulation IF I even ovulated. Has anyone fell pregnant during those dates or found out they were pregnant later or I’m good?
