Braxton Hicks vs real

I am due February 5 with baby #2. With my first baby I never had any contractions or Braxton Hicks or real contractions until I was in full-blown labor. A Few days ago I had two contractions, two nights in a row and I was assuming they were Braxton Hicks because I only had two and then they went away but they were excruciating! It would go from my lower abdomen to my lower back but then when I would get up they would go away. They were a minute apart. I then had a contraction last night that wasn’t as painful but it wasn’t going away when I stood up and walked around but I only had one. I am really confused! What does it sound like I am having?
