Braxton hicks or contractions??

Kenzi
I think I'm having Braxton Hicks?? I've got a tighten feeling or kinda like the baby is stretching in my lower abdomen. I'm 27w3d but my baby sits really low. FTM so don't really know exactly how contractions or Braxton hicks feel......  any advice or help? I don't feel like I need to go into the hospital!
