How long after mucous plug?

I'm 38w0d and this morning I lost my plug (it was a lot bigger than I expected). At my last appt 37w5d I was 90% effaced and a fingertip dilated and -2 station. FTM hoping to estimate when things will start. My parents are on a cruise for 5 more days. 😁 Any input would be appreciated!
