Could I be pregnant?

Cassie

Okay this is kind of long so I apologize in advance. I had a normal cycle, had sex the day of ovulation but then on cycle day 37 I started to bleed as if it were my period. I bled for 2 days but no clots. I haven’t tested bc I don’t have any symptoms other than fatigue, sore breasts and mild cramps that come and go If I am pregnant, I’d be 6 weeks today. What do y’all think? Is it possible or am I overthinking?
