Is this "regular" contractions?

So I'm 37+6, FTM.

I've been having bad lower back cramps since yesterday evening. A few hours later I started getting tightening across my abdomen very uncomfortable along with increasing lower back cramps. I ignored it for a few hours then began timing at 23:30.

The abdominal pain was happening every 10 minutes. I went to bed and slept for an hour and a half.

I woke at 3ish with pain and have been having increased tightening and pain. But they are not unbearable.

The question is if the contractions are "regular" or if the timing is more like braxton hicks.

Any help would be amazing!

Thanks
