Does anyone know ❔❓❔❓❔

My period ended on the 22nd and last 7 days , but I was spotting blood on and off. My next cycle is due on the 12th. But ive been having sex every other day since I ended my cycle and yes my S/o finish in me. I have been cramping down low on one side . I just had this brownish red looking blood the other day now its white cm. Did I still have ovulation? Where did the brown blood come from?
