Braxton Hicks or something else?

So I woke up this morning at 2:30 and realized I had these weird pains in my stomach going on. Only on my left side. It came up from low to higher up on my stomach, one pain seemed almost to run along my round ligament, the other ran up closer to the middle of my belly. They weren’t painful, they were almost like a cramping or tightening but it was pretty uncomfortable! This is my first so I’ve never felt anything quite like this, could it be Braxton Hicks? Or something else? Once it “went away” I thought, I rolled over onto my left side trying to get comfortable to go back to sleep, the side the cramps or tightening had been on, and as soon as I did the tightening immediately came back so now I’m awake and weirded out lol. Anyone have any ideas? I’m 25 weeks
