I am 4 weeks pregnant and I have light cramping after I urinate, just wondering if that is normal? Like should I worry?

Cramping is normal. This is your uterus stretching. I am not sure why you get it after you use the restroom.

A friend of mine was pregnant at the same time I was. She had severe period like cramping after she would go to the bathroom. She started spotting so she went to the doctor right away. Turned out she had a UTI. Maybe that could be it?
