Vaginal pain

I'm due tomorrow! I haven't really had any signs of labor though. Just regular bh contractions and cramping when I walk too much or get a little too active. I've been getting this weird pain. Ppl would call it lightning crotch, but it's not a sudden pain when baby moves and hits a nerve. It lasts a few minutes and just feels like painful pressure and it happens when the baby isn't even moving.
