braxton hicks??

I’m 34w3d and earlier I had a dull cramp like feeling in my lower stomach, kind of like my whole lower stomach felt so tight it “hurt” not a bad pain just annoying lol it lasted a few minutes but went away after I sat down for a little bit. It didn’t feel like period cramps, it was all over my lower stomach. does this sounds like BH, my muscles stretching or something else?

*Ive been more active than normal today, cleaning all morning then playing in the snow if that matters!
