Baby Moving or Braxton Hicks??

For the past week or so I’ve been having this uncomfortable feeling of pressure in my lower abdomen and then my baby head/butt (who knows lol) protrudes far out of my abdomen so I’ve been chalking it up to her just moving around and the fact that I’m carrying super low..... however, it just dawned on me, what if this uncomfortable pressure/tightness is Braxton Hicks rather than baby movement? This is my first child so I’m unsure of what they feel like. Anyone else going through similar things as I am? Currently 26 weeks.
