Bloody show

I’m 38 weeks and 2 days. So I have been having brown discharge since Monday afternoon, lost some of mucous plug. My back as been killing me, went to labor and delivery last night. I’m 4 cm. They sent me home because I had no contractions. Haven’t had anything today and felt very good beat i have in week. Came home form work just now wipes and had this.... do I go back to the hospital being there’s red blood or just wait?!
