Braxton-Hicks?

Amber • SAHM to a beautiful, smart, energetic 2 year old boy and his newborn brother!!
I am 27+4 with my second boy and the last few days it seems like if I get up and move around for more than just a few minutes, I start getting BH contractions. They aren't steady or anything, but I'm not sure if I need to call my dr or not over it. Anyone else experiencing this?
