Contractions cause butt to hurt?

I'm 40w tomorrow and ive been having mild contractions all day. My contraction pain affects my low back and low abdominal pain but I notice im starting to get sharp pains in my butt bone and butt hole (tmi, sorry). Is that normal with contractions? Is it baby putting pressure on things down there?
