Abdominal discomfort at thirty eight weeks pregnant.

Patient: Hi. I am 38 weeks pregnant with my first child. the past couple of days I have been having discomfort in my lower abdomen, it does not feel like contractions. it kind of feels like pressure but i am not to sure. she is moving like normal, but it makes it hard to move around because of the pain. its not excruciating or anything, just VERY uncomfortable. Should I be concerened??
