Braxton Hicks or round ligament?

C

23 weeks today and I’m curious how you tell the difference between round ligament pain and Braxton Hicks contractions. I’ve been experiencing something for a few days now that isn’t painful just maybe uncomfortable? I’ll get a tightening on my lower belly across the middle and then sometimes I feel tightening on just the right side. Sometimes it feels like growing pains (like I’ve eaten 10 thanksgiving dinners) though so it’s so difficult to tell what exactly it is
