Maybe Braxton Hicks?

I don’t know if this is the right spot for this, but....

So, I’ve had contractions with my one boy, but I had straight up contractions with him at 40w3d. Well, I’m 18w6d today and I felt the same pain as I did with the contractions with my oldest, just not as bad of a pain. Didn’t last long at all. Would that be considered as Braxton Hicks? Like I said, I only had contractions once with my oldest and they lasted for 2 hrs. I never experienced these with him, so I guess I’m just curious as to what’s happening😂 I haven’t felt anymore of them, so I guess that’s why I’m asking. Thank you!
