Help!

Fist time Mom here and just unsure of what’s going on! I’ve been having what I had considered Braxton Hicks for months but I’m now 38 weeks along. Do real contractions always hurt if your water hasn’t yet broken? My belly keeps getting firm and tight and it’s uncomfortable but I wouldn’t say painful. I’m well hydrated today and have been drinking more water since it’s been happening to make sure it isn’t a hydration issue and was lying down for several hours before it started. They’re timeable and have a pattern. Help!
