I need opinions

Last time hubby and I BD was July 31 before he left for a work trip. My period was due yesterday, but didn’t show. This morning I tested—it was negative. Mid morning I wiped and there was some blood on the tissue—I thought ok here’s AF. I haven’t bled since 🤔

Looking at my calendar, is there a chance this is implantation bleeding or just AF being weird lol
