Is it possible to only experience braxton hicks when walking around a long time?

I have no idea if what I'm feeling is braxton hicks or if baby is just making weird movements.. everything gets really tight and I feel pressure in my lower back, enough to make me want to bend over to relieve it.. it's only happening when I'm on my feet a long period of time. Is anyone else experiencing the same. What is this?
