Question about spotting.

I had my period last month on the 23rd. My fiancé ended up not pulling out during my period. Well during my ovulation week this month, we ended up having irresponsible sex and he didn’t pull out twice. Well ovulation day or supposed ovulation day I started spotting. I’ve been spotting brownish/red blood since Monday off and on. What do you think this is ? Maybe an early flow? Help 🤭
