Braxton Hicks

I’m 17+3 would it be normal to start feeling Braxton Hicks contractions? With my first I didn’t really notice any, but tonight I’ve started feeling some tightening in my lower stomach and i didn’t know if it would be possible to be Braxton hicks or maybe just the baby balling up? It feels to me more like a contraction sort of, idk. Lol.
