Braxton Hicks or nerve pain?

So for the past few days I've been getting a sharp stabbing pain on the left side of my stomach. I'm 38 weeks today, 2cm dilated and 50% thinned but I'm not sure if they are BHC or baby laying on a nerve or maybe even round ligament pain? The pain is not consistent at all I only have it maybe 2-3 times a day mostly at night when I'm in bed. What are your thoughts?
