help 😐

I'm a bit paranoid, I just finished my "period" which was for four days or more, I'm an irregular person so I start whenever my uterus pleases um, I did have sex but not when I was ovulating it was around when I knew I was about to start. Maybe I'm just assuming things or maybe It was the pancake and the bacon I just ate, having a full stomach isn't helping, uh no morning sickness or anything but let's just cut to the chase, am I pregnant?
