Show after blood?? Is it labor

On Sunday after intercourse I had a lot of bright red blood. Went to Hospital and it ended up being an irritated cervix. Monday I lost my mucus plug throughout the day (bloody show) and have had constant lower back ache(not contraction like- rather like a hurt muscle). Is labor nearing? Im just reaching the 34 weeks mark. I need some reassurance to when to phone my fiancé and tell him It’s time? He has an hour travel time to get to us!
