Should you track your contractions if they are Braxton Hicks?

This is my second baby so I am almost certain that I am having about half a dozen Braxton hicks contrations a day. They are not super painful just very uncomfortable tightning sensation. I can still talk and walk through them. I had a low lying placenta that resolved its self but now I have extra amniotic fluid which puts me at a higher risk of pre term labor. So should I be keeping track of my Braxton Hicks or just wait for the real deal??
