where’s AF?

hey ladies, so as you can see i’m 2 days left. However, my last period was june 22nd-27th. I got on the depo shot july 2nd and had unprotected sex the following night which was my fertile window. During ovulation time leading up to my scheduled period, I experienced sore boobs and mild cramping with 2 days of light spotting which was pink so I became a little worried. Fast forward to today, I had unprotected sex and my partner let off inside me... Am I protected or should I be concerned of potential pregnancy?
