Contractions or Braxton Hicks?

Hi, I’m 36.2 today and this is my second pregnancy but with my first I was induced and that was 3 years ago. I’m foggy on what a contraction feels like and what a Braxton hick feels like. I’m experiencing tightness in the belly pressure on my back and in my nether regions. It comes and goes, it’s enough for me to notice but not enough for me to stop what I’m doing in pain.

The only thing I remember with my son was feeling it in my back.

What do you ladies think? Contraction or BH? Help!
