Is bloody show a guarantee of labor soon?

Kara

So at my 39 week appt yesterday I had a membrane sweep done. The doctor said I'm 3-4cm dilated, 90% effaced, and -2 station. Last night and this morning I've been having my bloody show. Is having your bloody show a guarantee that you'll go into labor soon or could it still be another week or two?? This is my 2nd baby and I was induced with my first so I never experienced this stuff before.
