BH or actual contractions?

Been having waves of back pain since yesterday. Yesterday I would feel it in my hips & lower back for a few seconds through out the day. They went away for a while after a waking up today, but came back around noon now I’m feeling it from my hips all the way up to the middle of my back, now working it’s way up to the top as I type this. Sometimes it feels dull, other times sharp. When it happens it sticks around for quite a while. On a scale from 1 to 10 I would say the pain is about a 3, it’s just pretty uncomfortable. I did get confirmation that I was having contractions earlier yesterday when I went to L&D, but I wasn’t feeling them at the time. Could that have been BH at that time? What do you guys think?
