Labour?

Pregnant with my first baby and currently 40+1 I'm having what I think is contractions that are all around my back and front of my pelvis. But I haven't lost my mucus plug (that I'm aware of) and my waters haven't broke.

Is this labour or just really intense Braxton hix? I don't want to wake my husband up for a false alarm

Edit. I'm timing them and this looks like it!!!
