Pregnant after depo?

Yatavia

Okay so my bf and I are TTC, right. I went to my obgyn And gotten my nexplanon removed. Before she removed it, she gave me the depo shot and removed the nexplanon after. She told me to have protected sex for the next 7 days and my bf and I had unprotected sex 3days post shot. That third day was the last day for my fertile window also. I guess we’ll see how this goes 😬I just wonder is there still a possibility for a positive test ?
