consistent Braxton hicks?

Ch
I've been having consistent Braxton hicks accompanied with mild cramping and backaches since 7 this morning. No increase in intensity, all about 5-7 minutes apart. No water breaking, no bloody show, no loss of mucus plug.  I'm half expecting them just to fade away but so far they haven't. Has anyone else experienced this? 39+2 today.
Edit: they stopped completely around 8pm. I know it's good because it's prep for labor, but bring on the real labor already!!
