Warning pics of blood; I have 2 questions

Becca

37 weeks and 1 day , Had a cervical exam and came home used the bathroom and had quite a bit of bright red blood not sure if I should call my ob or just wait and see if it stops? Also another question, my ob said my cervix is open on the inside but the outside is closed does anyone know what that means? I meant to ask her but she was in a rush she was running late on appointments and I was also being rushed by my ride.
