Is it possible ? October month

Okay, so last time I had sex was the 1st-3rd on going sessions. (Also I was ovulating those days)

On The 15-18 I had a mild to heavy period flow. Then on my next ovulation days Oct. 30- until now I started cramping and having side pains so bad that I couldn’t walk. I’m still having pain until this day!

Is it possible I can be pregnant? Like I never experienced this.
