Braxton Hicks?

Sa

I am 37 weeks and haven’t had any BH up until now. Last night I experienced something new and was wondering if it sounds like BH. Baby was super active for a while. Then when I laid on my side to go to sleep, it felt like every few minutes she would like simultaneously poke out her elbow (or something) on my left side and butt (or something) on the right. When I felt my stomach I could feel two very distinct bumps (body parts), but my stomach overall seemed relatively hard I suppose. It’s hard to describe, and honestly, my stomach feels pretty hard all the time these days, because baby is so big! I had some mild cramping off and on. This went on for like an hour or so. Is this just something weird or maybe BH? Haha
