38 wks pregnant: What you are describing can definitely be a contraction. With how far along you are try to keep track of how often you are getting this sensation. If it becomes regular and constant every few minutes it's time to head to the hospital to be checked. Try to walk around as much as possible and you can take Tylenol (acetaminophen) to take the edge off if you get pain.
