Braxton Hicks?

So, FTM here and I’m not sure if what I’m feeling is BH or not. I know it doesn’t really mean anything, but I’m just curious. Everything I’ve read about them mentions period-like cramps and tightening across your stomach. I’ll randomly get what feels like gas pains and also cramps near my pelvis on the sides which feel like something you get sometimes if you’re running etc, but no period cramps and they only last a few seconds. My stomach will also get rock hard for maybe 30 seconds or so (not at the same time as the gas pains). Are these BH?! I’m confused lol
