Bloody Show, How long till labor begins?

Nina • Proud mommy
I'm 40 weeks, two days over due. Yesterday my Dr checked me and said I was a tight 1cm. Dilated. So to help speed up the process she stretched my cervix. I had inconsistent contractions once I got home that came and went. Now at 3:58 this morning I got my bloody show that she said would probably happen. How long after you get your bloody show before you go into labor? I had a few contractions afterwards but this morning nothing else.
