Can someone explain to me the difference between painful braxton hicks and just severe round ligament pain?

Every morning between 4-6 am I wake up with intense pain. It starts and peaks and then slowly fades away. Sometimes it's on my left side but sometimes on both sides and radiates just all around my abdomen. My stomach doesn't really feel hard though and drinking water makes them a little better? They sometimes come back to back.

If I try rolling over onto my other side it brings on another one. They hurt so much that it makes me grind my teeth and curl into a ball. This is also accompanied by back pain.

I'm so confused. 😔
